Description
WARNINGPlease read before purchasing Mishandling torsion springs, extension springs, tilt door fittings, tilt door hardware, tilt door springs, and associated door hardware can lead to severe injury or even death. It is strongly advised to seek professional installation. DO NOT attempt to install these springs or hardware unless you possess the appropriate tools, a reasonable level of mechanical expertise, ample experience, and sufficient upper body strength. Familiarize yourself with all instructions before commencing any work. In the case of doors equipped with two or more springs, it is imperative to replace all springs. DO NOT mix an old spring with a new one. Extension and tilt springs, torsion springs, in conjunction with their accompanying hardware, are constantly under intense tension. All tension must be carefully released from the springs before any work is undertaken. |
We strongly advise replacing both springs, as they tend to wear out around the same time. In most cases, they share the same age, workload, and level of metal fatigue. So, even if only one is broken from a pair, it's likely the other is nearing its breaking point as well.
