Description
The Intelligent Hardware narrow TS003 door chains are made from high
grade steel and what makes it stand apart from other door chains is that
it can exceed a breaking force of over 2kN (200Kg). This is achieved by
each link in the door chain being individually machine welded, providing
additional strength and resilience to forced entry!
What is TS003?
TS003:2012 is the most up to date specification for door chains and limiters
and is used in numerous standards within the industry including Secured by
Design. In order to reach TS003:2012, a door chain is tested to see if it can
withstand the effects of extreme and repeated force and abuse. The door
chain is put through tests of both ‘attack mode’ and ‘abuse mode’ and if
it is still intact after these tests have been carried out then it will pass.
