Tessi
TESSI is a trade security brand best known as a supplier of roller shutter locks—the practical, site-proven stuff used on roller shutters, gates, and similar metal closures where you want a straightforward mechanical lock that’s easy to fit, easy to replace, and hard to “accidentally” defeat with a big screwdriver and confidence.
Aldridge describes TESSI as having products used in the industry for over 20 years, with a range of shutter locks to suit multiple applications.
What TESSI is known for (the stuff you actually see on shelves)
-
Centre shutter locks (e.g., the 6410 pattern), typically a compact lock body that throws locking arms/bolts across the shutter/gate.
-
Bullet shutter locks in common formats like oval and round-faced models (e.g., 6460/6461), designed so the “bullet” tail engages into the shutter/door to prevent opening.
-
Genuine key blanks for the matching lock families (6410/6430/6460/6461 and cruciform variants like 6440).
Our range includes a selection of reliable, site-proven mechanical locks designed specifically for roller shutters, gates, and metal closures. This collection is split into two primary physical security categories to suit different installation requirements:
- Central Shutter Locks: Installed in the centre of the roller door, these locks feature dual extending side arms that link directly to your shutter's locking bars, securing the door into both sides of the frame. We stock standard (6410), narrow (6430), and ultra-narrow (6440) profiles to accommodate various door designs.
- Bullet Locks: Ideal for standard roller shutters, these locks fit into housings welded to the shutter frame, with a pin or tail that physically blocks the door from being raised. Choose between the Tessi 6460 Oval Bullet Lock or the TCP6461 Round Cylinder Bullet Lock depending on your existing housing.
Whether you are upgrading commercial premises or replacing worn-out shutter hardware, these straightforward, easy-to-fit security solutions provide dependable protection.
