These white Xiaheipi Window Jammer Locks are designed for homeowners seeking enhanced security on their doors and windows.

No, these window jammer locks are designed to provide an *additional* layer of security and restrict opening, not to replace primary deadbolts or other main locking mechanisms.
Ensure the interference arm is properly aligned with the window or door sash. Check that the lock body is securely fastened to the frame and not loose. Verify that the window/door frame is not warped or damaged, preventing a tight fit.
Pre-drilling pilot holes is essential. Use a drill bit slightly smaller than the screw diameter. If drilling into very hard material, consider a pilot hole lubricant or a drill bit designed for that material.
Check for any obstructions preventing the arm's movement. Clean the mechanism and apply a small amount of lubricant (like silicone spray) to the pivot point. Ensure the protective pad is not interfering with the movement.
Avoid harsh cleaning agents. For minor chips, touch-up paint suitable for metal surfaces may be used. Handle the lock with care during installation and operation to prevent further damage.
Setup:
Compatibility:
These locks are designed for use on most standard UPVC and PVC windows and doors, suitable for both inward and outward opening types. Ensure sufficient frame depth for proper installation and operation.
Care:
Wipe clean with a damp cloth as needed. Avoid using abrasive cleaners that could damage the paint finish. Periodically check that screws remain tight and the locking mechanism operates smoothly. The protective pad should be inspected for wear and tear.
