CISA 41320 Central Shutter Lock

The CISA 41320 Central Shutter Lock is a highly reliable security solution designed specifically for roller shutters on commercial, industrial, and residential premises. Installed centrally on the internal face of the shutter curtain, this lock operates two horizontal bolts that extend outwards into both side guides, providing balanced resistance against forced entry and prying.

A standout feature of the CISA 41320 is its double-throw mechanism. The first turn of the key throws the bolts 13mm, and the second turn extends them a further 13mm, achieving a robust 26mm total bolt projection. This deep engagement ensures maximum security for shopfronts, warehouses, and garage doors.

The lock is designed for convenient dual-sided operation and comes supplied with three keys: two keys specifically for operating the lock from the outside, and one key for use from the inside. With its durable build and polished brass cylinder, it is an ideal choice for both new installations and direct retrofitting.
