Heavy-duty window security bars can add a physical barrier to a window, but the right choice depends on the opening, how the bars attach, and whether the window must remain usable as an exit. The options below include adjustable interior tension bars and fixed exterior guards. Compare their sizes and installation needs carefully, and make sure any security measure still complies with local fire and building rules.

Artoshin Adjustable Bars: Best for Flexible Interior Placement
The Artoshin set includes six adjustable bars designed for indoor use on sliding windows and doors. Each bar adjusts from about 19.6 to 35.4 inches and uses a built-in spring to create tension between the sides of an opening. That makes this a different kind of solution from the fixed, screw-mounted guards in this roundup.
The adjustable range can be useful when you need to fit more than one opening, but measure each location before ordering. A tension-style bar needs a suitable, stable surface at both ends; it is not a universal fit for every window frame. The product description also presents the bars for other household uses, but those uses do not replace checking that a bar is secure and appropriate for its intended location.
Because these bars sit inside, they avoid the exterior installation required by the fixed guards below. Their spring-tension design is also easier to reposition than a permanently mounted guard. However, the product details do not describe a keyed lock or a fixed-frame attachment, so consider whether a tension bar provides the level and type of security you need. It should not be treated as a substitute for a compliant emergency exit.
Pros:
- Six bars are included in the set.
- Adjusts from about 19.6 to 35.4 inches.
- Designed for indoor use on sliding windows and doors.
- Spring tension allows adjustment without the fixed-guard format.
Cons:
- The adjustable range will not fit openings outside its stated dimensions.
- The supplied details do not specify a screw-mounted or keyed locking system.
Verdict: Choose the Artoshin set if you want multiple adjustable interior bars and your openings are compatible with its stated range.
Housagies Magnum 36-by-48-Inch Guard: Best for Larger Windows
This Housagies guard is a fixed, black exterior unit sized 36 by 48 inches. Its description highlights robotic welding and non-reversing safety screws, features intended to make the frame and its attachment harder to tamper with from outside. It also has a decorative spear-point pattern, so it looks more finished than a plain grid.
Fit and mounting are important here. The listing says the bracket is sold separately and that the appropriate accessories depend on the window’s shape and size. You will need to confirm the opening dimensions and choose compatible mounting hardware before installation; the guard’s stated size alone does not confirm a fit for every window.
Compared with the Artoshin tension bars, this model is a more permanent exterior barrier and does not offer the same adjustable placement. That can suit a window where a fixed guard is the goal, but it also makes planning for window access and emergency escape especially important. Check local requirements before adding an exterior guard to any window that may serve as an exit.
Pros:
- Fixed 36-by-48-inch format for openings that match its dimensions.
- Described as having welded joints and non-reversing safety screws.
- Rust-proof construction is stated in the product description.
- Decorative spear-point design in a black finish.
Cons:
- Mounting brackets are sold separately.
- Requires careful sizing and exterior installation rather than simple repositioning.
Verdict: Consider the Housagies Magnum if your window suits its 36-by-48-inch frame and you are prepared to source the right brackets and plan the installation.
Grisham Spear Point 36-by-36-Inch Guard: Best for a Smaller Fixed Opening
The Grisham listing describes a white, 36-by-36-inch exterior window guard with a spear-point pattern. Its product details call out welded construction, non-reversing safety screws, and rust-resistant materials. The square size distinguishes it from the larger 36-by-48-inch Housagies option, so it may be a better starting point for a window that matches the smaller dimensions.
As with the Housagies guard, the bracket is sold separately. The supplied listing names the product Grisham but identifies Housagies as the brand, so confirm the listing details and mounting accessories before purchasing. The design is intended for fixed installation, not for quick removal or adjustment like an interior tension bar.
A fixed exterior guard can create a substantial barrier, but it can also limit access to the window. Before installing it, consider whether the window is part of an emergency escape route and verify applicable local rules. Measure the actual opening and account for the way the guard and brackets are meant to mount rather than relying only on the product’s nominal dimensions.
Pros:
- 36-by-36-inch size for a smaller opening than the Magnum model.
- White finish and decorative spear-point pattern.
- Product details specify welded construction and non-reversing screws.
- Described as rust-resistant.
Cons:
- Brackets are sold separately.
- Fixed exterior installation may restrict window access or emergency egress.
Verdict: This is a reasonable fixed-guard option to investigate when a white 36-by-36-inch frame matches your window and you have confirmed the bracket and safety requirements.
Ritabiity Spear Point Guard: Best for a Decorative Iron Look
The Ritabiity is a fixed exterior guard made from iron, with a high-temperature baking-paint finish and a decorative pattern of hearts and curves. Its description specifies tubes that are 0.6 inches wide and presents the guard as a sturdy option for homes and other settings. Unlike the spear-point designs above, its appearance is more ornamental.
The product details describe installation as mounting brackets and then fitting the guard outside the window, with almost no assembly. However, they do not provide an overall frame size or state whether mounting brackets are included. Check the listing for exact dimensions and included hardware before relying on it for a particular opening. The supplied product data also marks this listing unavailable, so availability may be a limiting factor.
This model could suit someone who wants a fixed guard with a decorative look, but the lack of a stated overall size in the supplied details makes fit harder to assess than with the two Housagies options. It is also not adjustable like the Artoshin bars. As with any fixed guard, confirm that installation will not block a required exit.
Pros:
- Iron construction with a painted finish, according to the description.
- Decorative heart-and-curve pattern.
- Product details describe a straightforward bracket-mounted installation.
- Intended for use in several types of residential and lodging spaces.
Cons:
- The supplied product details do not state the guard’s overall dimensions.
- The supplied availability data marks it unavailable.
Verdict: Consider the Ritabiity only after confirming that it is available, that its dimensions fit, and that its mounting hardware meets your needs.
How to Choose Heavy-Duty Window Security Bars
Measure the opening and check the mounting space
Measure the window where the bar or guard will sit, not just the glass pane. For the Artoshin bars, compare the available space with the stated 19.6-to-35.4-inch adjustment range. For fixed guards, compare the product’s stated frame dimensions with the window and confirm how the brackets attach. Leave enough room for the frame and hardware to sit as intended.
Choose between an interior tension bar and a fixed guard
An adjustable interior bar is easier to position and does not require the same exterior mounting approach as a fixed guard. Its fit depends on the opening and on having suitable contact points for tension. A fixed guard creates a more permanent barrier, but installation takes more planning and may require separate brackets. Decide which setup fits your security goals and how you use the window.
Verify brackets, fasteners, and installation details
Do not assume that mounting hardware is included. The Housagies Magnum and Grisham listings state that brackets are sold separately. The Ritabiity details refer to brackets but do not specify whether they are included. Check the current product listing and instructions before buying, and use hardware suitable for the window and surrounding structure.
Consider emergency escape and local rules
Security bars can make a window harder to open or reach from outside. That may create a serious problem if the window is needed as an emergency exit. Before installing a fixed guard, check local fire and building requirements and consider how occupants would leave the room in an emergency. Do not block a required egress window.
Look at materials and finish in context
The product descriptions cite steel for the Artoshin bars, welded construction and rust-resistant materials for the Housagies guards, and iron with a painted finish for the Ritabiity guard. These descriptions help compare the stated designs, but they do not establish how any product will perform in every climate or installation. Consider the exposure to weather and follow the manufacturer’s care and installation guidance.
Match the design to the room and your routine
Fixed exterior guards are visible from outside and can change the appearance of a window. The Housagies and Grisham options use spear-point details, while the Ritabiity has a curved decorative pattern. An interior tension bar may be less visible from outdoors, but it still needs to be correctly placed and checked. Choose a design that fits both the window and your everyday access needs.
Frequently Asked Questions
Are adjustable tension bars as secure as fixed window guards?
They use different installation methods. The Artoshin bars rely on spring tension, while the Housagies, Grisham, and Ritabiity products are described as fixed exterior guards. The supplied details do not establish that one style is equally secure in every situation, so choose based on the opening, installation, and level of protection you need.
How do I know whether an adjustable bar will fit?
Measure the space where the bar will sit and compare it with the stated adjustment range. The Artoshin bars adjust from about 19.6 to 35.4 inches. Make sure the bar can rest securely at both ends and follow the product’s installation directions.
Do the fixed guards include mounting brackets?
The Housagies Magnum and Grisham listings say brackets are sold separately. The Ritabiity description mentions mounting brackets but does not clearly state whether they are included. Check the product listing and included-parts information before ordering.
Can window security bars block an emergency exit?
Yes. A fixed guard or a bar that prevents a window from opening can interfere with emergency escape. Check local fire and building rules, and do not install a guard in a way that blocks a required exit.
Can these bars be used on sliding doors?
The Artoshin bars are specifically described for sliding doors and windows. The other products in this roundup are described as window guards, so do not assume they are suitable for a door.
Do the fixed guards fit every window of the same general size?
No. The listed dimensions are a starting point, not a guarantee of fit. Window shape, frame construction, mounting position, and bracket choice can all affect compatibility. Measure your opening and confirm the installation requirements before buying.
Final Recommendation
For an adjustable interior option, the Artoshin six-pack is the clearest fit when your openings fall within its stated range. For a fixed exterior barrier, compare the Housagies Magnum at 36 by 48 inches with the Grisham at 36 by 36 inches, while accounting for their separately sold brackets. The Ritabiity offers a decorative iron design, but confirm availability and dimensions first. Whatever you choose, verify fit and mounting details, and preserve any window needed for emergency escape.
