Adjustable pressure-mounted security bars are a practical option for apartment windows because they add a physical barrier without requiring permanent installation. The Keplrend bar is best for renters seeking a no-drill fit with fine adjustment, while the DEROFIT two-pack suits households securing more than one opening. For shorter windows, the KUANVE two-pack has a compact range; the Gadgetzan four-pack is best for multiple windows. These products are removable bars, not fixed metal window grilles.

Keplrend Adjustable No-Drill Security Bar
Best for: Apartment renters who want a removable pressure-mounted bar with several adjustment features. The listing describes use with horizontal sliding windows and vertical up-and-down windows, as well as sliding glass patio doors.
Pop-up pins provide coarse sizing, while the threaded rubber foot allows finer adjustment. Double lock nuts are intended to hold the setting, and non-slip pads help protect tracks from scratches. Installation and removal require no drilling, making the bar portable for temporary use.
Why it was selected: Its listed adjustment mechanisms and pressure-mount design address common renter needs. Limitation: The provided product details do not state a length range, so measure the opening and confirm fit before choosing it.
DEROFIT Two-Pack Security Bars
Best for: Households that need bars for two openings or want a broad adjustment range. Each bar adjusts from 16 to 51 inches using telescoping and extension sections, according to the listing.
The removable bottom section lets the bar work with sliding windows and doors. The product is also described as a physical deterrent against forced entry and as a way to reduce the risk of children or pets opening a window or door. Choose this set if a single bar’s coverage is not enough for your home.
Why it was selected: The two-piece package and stated wide range offer flexibility across different openings. Limitation: Check that the complete assembly fits your window track and that each bar can be positioned securely.
17–50 Inch Adjustable Metal Security Bar
Best for: People securing a wider opening who want a portable bar for home or travel. The listed size range is 17 to 50 inches, and the bar is made from painted metal with a one-inch diameter.
The product has rubber tips and is described as requiring no drilling, with assembly intended to take one to two minutes. Its portability may suit apartment residents who want a removable option or travelers who want to carry a security bar.
Why it was selected: Its specified range covers many wider openings, and the removable setup suits temporary use. Limitation: It will not fit openings narrower than 17 inches or wider than 50 inches; measure before ordering.
KUANVE Two-Pack Short Window Bars
Best for: Shorter sliding windows that need a compact adjustable bar. The two bars measure 15.7 to 27.5 inches, and the listed diameter is 0.87 inch.
Each bar uses a built-in spring and rubber ends to create tension against the opening. The listing describes an electrostatic-sprayed surface intended to resist rust and a smooth finish. Choose this set if the measured opening falls within its narrower range and you need two bars.
Why it was selected: Its compact dimensions make it a more suitable choice than longer bars for smaller openings. Limitation: The maximum stated length is 27.5 inches, so it is not intended for wider windows.
Gadgetzan Four-Pack Window Security Bars
Best for: Apartment residents who want bars for several windows. This package contains four adjustable bars with a stated range of 17 to 33 inches.
The listing describes a metal construction with an electrostatic-sprayed surface intended to help prevent rust. It also presents the bars as a way to limit children or pets opening windows. Compare the measured width of each opening with the range before selecting this multi-bar set.
Why it was selected: Four bars can cover more openings than the single-bar products in this list. Limitation: The maximum length is 33 inches, so these bars are not suited to wider windows.
Buying Guide: How To Choose Apartment Window Security Bars
How should you measure a window?
Measure the opening where the bar will sit, following the product instructions. Compare that measurement with the full adjustment range, not just the bar’s minimum length. A bar that is too short or too long may not fit securely. Check each window separately because apartment openings can differ.
Should you choose a pressure-mounted or drilled bar?
The products here are described as adjustable, removable bars, and some explicitly use pressure mounting without drilling. That can suit renters who want to avoid permanent changes. Confirm the installation method and any frame or track requirements in the product details. These products are not fixed grilles or a substitute for checking local building and fire-safety rules.
How many bars do you need?
Choose a single bar when securing one opening. A two-pack can cover two suitable openings, while the Gadgetzan four-pack is intended for multiple windows. Match the dimensions of each bar to the opening it will secure rather than assuming one size fits every window.
What should families consider?
Several listings describe their bars as helping prevent children or pets from opening windows. Treat a bar as one layer of safety, not complete protection. Follow the product’s installation instructions, check that it remains firmly positioned, and consider whether the window must remain available for emergency exit.
Frequently Asked Questions
Do window security bars require drilling?
Some listed options use no-drill or pressure-mounted installation. Check the specific product instructions because installation details vary.
Can these bars fit every apartment window?
No. Each product has a stated size range, and the Keplrend listing supplied here does not specify one. Measure the opening and confirm the fit before buying.
Are adjustable bars the same as fixed window grilles?
No. These products are removable bars positioned in a window opening. Fixed grilles are a different type of installation.
Which option is best for a small window?
The KUANVE bars are the most compact option listed, with a range of 15.7 to 27.5 inches. Confirm that your measured opening falls within that range.
Which product covers the most openings?
The Gadgetzan set includes four bars. Its stated range is 17 to 33 inches, so it is best for multiple openings that fit those dimensions.
