Tessi is a reputable manufacturer of high quality, versatile roller shutter locks that are designed to provide a high security locking system for a range of shutters. Tessi locks are suitable for use with any aluminium or steel roller shutters. They can be used in a variety of different settings as well, including factories, shopping centres, homes, warehouses, and any residential, commercial or industrial premises. The Tessi selection of central shutter locks work by securing the roller shutter to the frame and locking it on either side. When locked, the arms are thrown open and project to secure the shutter. The deadbolt can be locked or unlocked from either side by the key. Two keys are provided with each Tessi lock product. Apart from the standard Tessi Roller Shutter Lock, the Tessi Euro Shutter Lock is also available, which features a Euro cut out and is suitably sized for most Euro Cylinders. Tessi locks provide a superior locking system compared to other roller shutter locking options. They are designed to create a reliable and solid barrier against unwanted intrusion or burglary, whether it is in the home, a factory, retail store or elsewhere. Tessi locks can be obtained from easylocks, which is the chief supplier of Tessi products in the UK.
