Delivered on time, with the products described: springs, winding bats, & plastic bushing. Quick install, but apparently I measured wrong, so these total length I bought was larger (which is good as there is less stress on the spring). However this did mean that I needed more than the generic rule of 30 1/4-turns of preload. I wound up with 38 1/4-turns per side for the door to balance when open 3' (per familyhandyman.com recommendations). Would definitely do it again.
High-Cycle Springs: For longer lasting performance, choose our 100,000* high-cycle springs that are now powder coated. These springs are larger in length and inside diameter, resist rust, last longer than traditional springs and are guaranteed for life. Great for larger families, multiple vehicles and where the garage door is used more like your front door.

6.1 It is time now to unwind the old spring that is not broken. A few warnings are in order. NEVER, NEVER, NEVER touch a set screw without first inserting a properly fitting bar into the winding cone! Also, do not use box or socket wrenches for the set screws. If the cone slips, the wrench could break your hand in 10 spots before unwinding completely. It's my guess that this is the number one cause of trips to the emergency room for inexperienced homeowners fixing or replacing their springs.

2.3 Beware of older winding cones. These older Crawford and McKee torsion spring cones were made for 5/8" bars. Sometimes, however, the holes are too small for 5/8" bars. Whatever you do, don't use a 1/2" bar; instead, grind down a 5/8" bar to fit. I recently had a McKee spring let loose after winding because I used a 1/2" bar when my 5/8" bar wouldn't fit. Just before it let loose I was telling myself, "This is not safe." And it wasn't. The only safe way to replace these older springs is to make a winding bar for each hole of each cone.
If you are in an emergency situation, you can lift the door manually while using the garage door opener, but this is not recommended. The door could get stuck halfway up and then slam the rest of the way down. This could cause injury. The ideal solution is to call a Twin Cities garage door repair company to come quickly and repair the spring so that normal operation can be restored and so you are not in a situation where you find yourself having to attempt manual lift with or without the assistance of the opener.
• Extension springs: Garage door extension springs stretch to provide lifting power for the door. These springs are typically made of steel and mounted above the horizontal track of the garage door. A safety cable should run through your extension springs to prevent possible injuries or property damage. Extension springs are the most common type of garage door spring for residential use and can break after excessive usage.
