Hardware
Adjustable Sliding Window Locks — 10-Pack Aluminum Stoppers
Product description
What you get: a set of ten adjustable track stoppers designed for both horizontal and vertical sliding windows and doors. Each piece features an adjustable thumb screw for clamping into place and a vinyl-lined contact surface to cushion the frame.
Materials and sizing: constructed from heavy-duty aluminum for strength and corrosion resistance. The inner vinyl lining protects against scratches and increases grip. The locks accommodate track clearances of approximately 28–36mm and clamp to tracks up to 7/32" wide using the included thumb screws.
How it works: these stoppers slide into the window or door track and are tightened with the thumb screw to lock the sash at the desired position — fully closed or slightly ajar to admit air. No drilling or permanent hardware is required, making them suitable for renters and temporary installations.
Common uses: secure patio doors, sliding glass doors, residential vertical and horizontal windows, window air conditioner installations, camper windows, and childproofing setups. The vinyl insert helps prevent marring while holding the sash steady.
Pros

Cons
- Vinyl inserts may not be permanently attached

VerdictA practical, no-drill solution to secure patio doors, sliding windows and window AC installations. Built from heavy aluminum with vinyl inserts, these adjustable stoppers offer reliable holding power and simple installation. Fit and the vinyl insert attachment are the main factors to check before buying.

Butler 5/5
Essential for child safety
Stops kids from opening windows and holds them firmly. Very robust and easy to mount — it doesn't budge when tested.

Not ideal for vinyl frames
The black pads detach quickly and they don't fit vinyl tracks easily. They're fiddly to remove and I worry about wear on the track — better for metal frames.

Acceptable, nothing special
Serviceable product. Probably won't repurchase.

Annette BardgeThe material is beautiful the color is fine for it, and the fit is 5/5
Surprisingly simple install
Installation was a breeze and the materials feel solid. I felt more secure as soon as they were in place.

Inner padding can come loose
They perform fine, but the vinyl inserts aren't fixed and can fall out when you loosen the screw. I glued mine in place to prevent loss.

Perfect substitute for rods
I hadn't seen these before — much cleaner-looking than a pipe. Small size fits snugly and seems secure; the dog hasn't disturbed them.
