I have recently moved into a newish house,and all the doors off the hallway have a chain at the hinge side of the door. This closes the door automatically, but the tension is so strong that twice I have caught, and badly bruised my fingers, once a visiting child, and almost decapitated the cat a number of times!
I've looked on the net, and discovered it is a Perko (or similar) fastener. I was considering just disconnecting them, but then thought this may invalidate my house insurance in case of fire.
Could anyone suggest how I loosen the tension- I need step by step idiot proof instructions- and is it something I could do myself, or would it require 2 people: does it require a tool (if so what is it called and where would I get one) or is it best left to a professsional?
Many thanks for any advice- Julia
