Our take on the Extension Spring Lift Containment Hardware Kit for doors up to 200lbs

This is a complete replacement hardware set for the extension spring system on 7 ft and 8 ft garage doors weighing up to 200 lbs. It bundles four 3-inch heavy-duty pulleys rated for 200 lbs, a pair of 1/8-inch 7x7 strand spring cables, a pair of matching safety containment cables, pulley straps with a containment cable offset and nylon bushing, cable clips, S hooks, eye bolts and the nuts, bolts and washers to fit them. The containment cables are the feature that sets it apart from a bare pulley-and-cable kit: they keep a broken spring or cable from whipping loose. It suits a homeowner or tech rebuilding a worn extension spring setup in one order, and it does not fit torsion or TorqueMaster systems.

Questions and answers

Does this kit fit torsion springs?
No. It is made for extension spring systems only and is not compatible with torsion or TorqueMaster setups.
What door heights and weights does it cover?
It is built for 7 ft and 8 ft doors weighing up to 200 lbs. The cables are 160 inches long to suit those heights.
Are springs included?
No. The kit covers the pulleys, spring cables, safety cables, straps, clips and fasteners. The extension springs themselves are separate.
What is the containment cable for?
It runs alongside the spring system so a broken spring or cable is held in place instead of flying loose. The pulley straps include an offset for routing it.
Can I install it myself?
Extension springs are under heavy tension. If you are not confident with the door clamped and the springs relaxed safely, have a garage door technician do the swap.
