garage door springs with no safety cable
Hi! A friend of mine recently had a new house built, and his two garage doors (installed by the builder) don't have a cable that goes through the springs to prevent them to swing back and forth in the event that a spring breaks or comes loose (as it already happened twice) but luckily for him the cable snagged on the track so nobody was injured.
I think the Canadian building code requires such safety cable, but when he told that to the builder, he laughed at him. Could you please tell me if it is indeed required by code, and knowing the exact article would be appreciated, as he will be able to go to the library and show the code to the builder. Thanks.
