Child And Burglar-Proof Cam Type Button Release Sash Locks

The Mark Series windows incorporate a premium dual-action sash lock. Not only does this create a weather-proof seal, it also prevents the window from being forced open by intruders on the outside, or by children on the inside. This is done without the use of keys in locks.

In addition to this, BIL-DEN is proud to have incorporated and trademarked "Limit Latches" into all double hung and side slider windows.

These unique latches allow ventilation, while preventing the window from being opened beyond the limit that you set, for the safety of children and pets as well as for security reasons.

NOW YOU CAN RELAX.
