Delmoar Fixed Window Safety Guard 19”x 38” *2 Pack Adjustable Width Prevents Accidental Falls,Non-Egress, Tamper Resistant Screws Included,White

Why I installed this guard

A few windows in my house sit low enough that an inquisitive kid (or an overconfident pet) could push a screen and lean out farther than I’m comfortable with. I wanted a clean, fixed barrier that still let me ventilate the room. I tested the Delmoar window guard in white, the 19-by-38-inch two-pack, on a second-floor double-hung window and a side-yard window that opens to an easement. It’s a non-egress, fixed design—so it’s not meant for bedrooms or any window where the guard would block an emergency exit—but for living areas and hallways, it’s exactly the kind of passive safety measure I like: always on, nothing to latch or forget.

Design and build

The guard is a fixed-height panel with a telescoping width mechanism, designed to sit over the interior casing of a vertical window. The model I used fits a height of 19 inches and adjusts in width from 21 to 38 inches. The two-pack is useful: you can cover two separate windows or stack them to increase coverage on a taller opening (within reason and with proper anchoring).

A few design choices stand out:

• Bar spacing is 3.8 inches. That’s tighter than the common 4-inch guideline used in many safety contexts, which is exactly what I want in a child-safety application.
• The white finish blends well with painted trim and doesn’t jump out visually. It’s not ornate; it’s a practical, minimal look that keeps sightlines open.
• Tamper-resistant screws are included. This isn’t a high-security bar, but the fasteners make casual removal much less likely.
• The frame’s sliding sections lock down mechanically during installation, so once set to width and fastened into the window casing (preferably the framing behind it), the assembly feels monolithic.

The materials are robust for the category—rigid enough that I couldn’t flex the bars by hand. Welds are tidy, and the finish on my set was even, with no sharp edges or burrs. It’s not heavy, but it reads as sturdy, which matters for both safety and perceived deterrence.

Installation: straightforward with a few tips

If you’re comfortable with a drill/driver, the install is quick. Here’s how mine went and what I’d do again:

• Measure twice. The height is fixed, so confirm you’ve actually got 19 inches of clear, flat surface on the interior casing. Width is more forgiving, but I still marked the midpoint of the window and the guard so I could center it cleanly.
• Dry fit and set the width. Extend the guard to the casing edges and snug the telescoping sections so they’re square. A torpedo level helps here—get it plumb before you commit to holes.
• Pre-drill pilot holes. Especially if your casing is hardwood or MDF, pre-drilling reduces the chance of splitting and makes for cleaner screw seating. My best installs go into the underlying framing; use longer screws if needed to bite into solid wood behind the casing.
• Get a helper for the first two screws. Holding the guard with one hand while driving the initial fasteners is possible, but a second set of hands makes it easy and keeps the alignment perfect.
• Use the tamper-resistant driver. My kit included the matching bit for the supplied screws; if yours doesn’t, pick one up to avoid marring the heads.

From opening the box to tightening the last screw, my first guard took about 25 minutes. The second went on in roughly 15. Hardware in my box was taped to the bars—nice touch for not losing small parts. On one unit, I did have a single missing screw; not a showstopper, but worth checking before you start.

In daily use

The guard does what it should without calling attention to itself. With the lower sash raised for airflow, the 3.8-inch spacing blocks a child’s head and shoulders and prevents a pet from squeezing through. It hasn’t rattled or buzzed in wind, and there’s no appreciable flex when leaned on. On the side-yard window, the visual barrier also reads as a deterrent from outside. It’s not a substitute for proper security hardware, but it adds friction for anyone thinking about a quick entry through an open window.

Visibility through the bars is better than I expected. The thin, evenly spaced members keep the view and daylight intact. Cleaning the window is still straightforward—screens come out as usual, and I can reach the sash locks. If you routinely tilt your sashes inward for cleaning, measure clearances; the guard sits proud of the casing by the thickness of its frame, and some windows need an extra inch or so to tilt past it.

Limitations and compatibility

A few constraints to keep in mind before you buy:

• Non-egress by design. The fixed, tamper-resistant install means it shouldn’t be used in bedrooms or any location where the guard would interfere with emergency egress. Check your local codes; this matters.
• Vertical windows only. It’s intended for single- and double-hung windows. It’s not suitable for horizontal sliders or casement/hinged types. If you have those, look for a hinged egress-rated guard instead.
• Flat, solid mounting surface required. Ornate profiles, deep returns, or very narrow casings can complicate installation. You can use spacers, but the safest approach is solid anchoring into the framing behind the casing.
• Fixed height. At 19 inches tall, it covers the risky lower portion of a window well, but very low sills or unusually tall openings may benefit from stacking guards. If you stack, ensure fasteners and layout maintain proper spacing and structural support.
• Minimal documentation. My box included basic info, but not a detailed template or step-by-step. It’s not complicated, but first-time DIYers might wish for clearer guidance.

What I’d change

A few refinements would make this kit even better:

• Include a printed drilling template and clearer placement guidance for different casing widths. It would simplify centering and speed up installs.
• Standardize hardware counts across all boxes and add a couple of spare screws. Missing a single fastener can stall an otherwise quick project.
• Offer two screw lengths out of the box: a shorter set for solid hardwood casings and a longer set for reaching framing behind MDF or plaster-over-lath.

None of these are deal breakers, but they’re easy wins that would reduce friction for DIY users.

Who it’s for

• Parents and caregivers who want a passive safeguard on playroom, hallway, or living room windows that are routinely opened for ventilation.
• Pet owners with ground- or second-story windows where a screen isn’t enough to prevent an excited animal from pushing out.
• Homeowners looking for a light deterrent on side-yard or alley-facing windows they like to keep open when home.
• Property managers and short-term rental hosts who want a consistent, clean-looking barrier in non-bedroom areas without installing more industrial-looking bars.

If you need code-compliant egress in the same spot, or you have casement or horizontal sliders, look for a hinged or quick-release model specifically rated for those use cases.

Value and alternatives

Fixed guards like this sit between pressure-mounted “no-drill” options and hinged, code-rated egress guards. Compared with pressure-fit designs, the Delmoar’s permanent mounting is far more secure and tamper-resistant. Compared with hinged egress models, it’s simpler and usually more affordable, but it trades away quick-release capability—again, why it’s not for bedrooms. Within that niche, the adjustable width and tidy finish make it easy to standardize across several windows without custom ordering.

Recommendation

I recommend the Delmoar window guard for anyone who needs a clean, sturdy, non-egress barrier on vertical windows in living spaces, hallways, or other non-sleeping areas. It installs quickly with basic tools, the 3.8-inch spacing is appropriately protective, and the white finish blends into typical interior trim better than more industrial alternatives. Be mindful of the non-egress limitation, verify you’ve got a flat mounting surface and access to framing, and check the hardware before you start. With those caveats in mind, it’s a practical, reassuring upgrade that does its job quietly and well.
