Fischer 571729 Anti Intrusion System for motorised Roller shutters, Black, B Lock 5

B-Lock 5 joints: anti-theft system that works like a spine, wrapping itself on the roller together with the roller and tightening automatically when the roller is closed. Anti-intrusion for fully automatic electric shutters SIMPLE: the roller blind lock that installs in just a few steps without removing the roller winder. Simply tighten the two loops on the roller and slide the joints along the roller blind SAFE: Anti-intrusion that resists lifting by preventing the use of levers under the roller shutter. UNIVERSAL: suitable for most standard electric blinds. Installs on both new and existing shutters INNOVATIVE: The rounded ridges of the rings prevent the roller shutter slats from marking during winding, thus preserving the aesthetics CONTENTS: Each B-Lock 5 Kit contains two rings and a four-joint bone. You must purchase at least two kits per roller shutter. B-Lock systems must have a maximum distance of 10 cm from the edge and 80 cm between them. If this measure is not met, insert an additional B-Lock intermediate kit., Manufacturer: Fischer
