Adjustable Aluminum Sliding Door & Window Lock

Secure sliding doors and windows in seconds-no tools required.

This adjustable sliding door and window lock is engineered from robust metal alloy for reliable, long-term security in homes, offices, and commercial spaces. The compact clamp-style design fits most vertical or horizontal sliding windows and many sliding doors with a track rim width of approximately 2.5-4 cm (about 1-1.57 in). A simple thumb-screw mechanism tightens the lock firmly onto the track, helping prevent the sash from being forced or pried open from the outside.

Designed for everyday use, this lock allows you to fully secure a window or door in the closed position, or to safely limit the opening for controlled ventilation. It is especially useful where additional security is needed without installing permanent hardware-ideal for rented properties, offices, and spaces where drilling into frames is not an option. The sleek, low-profile body in neutral colors (black, grey, or brown) blends easily with most modern window and door frames.

Why It's a Smart Choice

• Tool-free installation - Clamps directly onto the track; simply position and tighten the thumb screw-no drilling, screws, or special tools.
• Adjustable and reusable - Fits many sliding window and door tracks (approx. 2.5-4 cm wide) and can be moved or removed in seconds as needed.
• Added safety and access control - Helps deter intrusion, restricts how far windows open, and supports safer ventilation in homes, offices, and other properties.

FAQ

Q: Will this lock fit my window or door?
A: It is designed for most vertical or horizontal sliding windows and many sliding doors with a track rim width of about 2.5-4 cm (1-1.57 in). Measure your track width before ordering.

Q: Do I need tools or to drill into the frame?
A: No. The lock clamps onto the track using an integrated thumb screw. It installs and removes without tools or permanent modifications.

Q: Can it be used to keep windows partially open for ventilation?
A: Yes. Position the lock at the desired opening width and tighten. This helps limit how far the window or door can slide.

Q: Is this suitable as an additional child safety measure?
A: It can help restrict how far a child can open a sliding window or door. However, it should be used as part of a broader safety approach and not as the only childproofing device.
