Security Jammer Kit

The Security Sash Jammer Kit is a highly effective and easy-to-install security upgrade designed to reinforce entry points around your property. By physically “jamming” the opening to its frame, the device restricts access and prevents forced entry, even if the lock is compromised.

Ideal for enhancing the security of uPVC doors and windows, this versatile jammer is also suitable for letterboxes, cupboards, internal doors, and more. Whether you’re protecting a home, rental, or office, the sash jammer provides a visible and robust deterrent to opportunistic intruders.
