DOUBLE SECURE
Window handle lock instead of window handle with adjustable steel bolt.
Reliably lockable windows should be basic equipment in terms of security of your home. Protect your windows with this lockable additional security device. The security's crimping steel deadbolts can withstand over a ton of pressure. Since the deadbolts are adjustable, they can be universally attached to aluminum, vinyl and wood windows. The security device is mounted on the window sash. It can be operated like a conventional window handle and functions as a burglar and child safety device.
