Tessi 6440 Ultra Narrow Central Shutter Lock

The Tessi 6440 Ultra Narrow Central Shutter Lock is a compact and reliable security solution designed specifically for roller shutters and gates. Engineered for installations where space is at a premium, its ultra-narrow profile allows it to fit seamlessly into tight shutter channels.

Typically mounted in the centre on the inside of the door, this lock features dual-extending side arms. When the key is turned, both arms shoot outwards to connect with the shutter's locking bars, securely anchoring the shutter into both sides of the frame for enhanced protection. The polished brass cylinder protrudes through the door, offering smooth and convenient key access from the exterior.

Supplied complete with two keys, the Tessi 6440 is an ideal choice for securing commercial or domestic roller shutter doors.
