Rated 2 out of 5Â by Haditwiththesesprings Should be called 'over built'. Spring rating is way off.
I have an 8x7 3-layer insulated garage door. I called Clopay with the serial number and asked what the door weighs. I was told the door weighs 127lbs and I should use a 120lb spring.
I had the 110lb springs already so I figured it was worth trying. The basically launch the door right off the track. I have them adjusted so loose that the door closes almost 1/3 of the way before the spring is engaged (this is after a normal adjustment and almost losing body parts to the garage whipping off the ground and the pulleys and cables snapping around).
The directions are horrible - the worst I've ever come across and I have been putting stuff together and fixing houses for decades. It has been a full week to finally figure out the right way to install the springs, and to my misfortune the spring tension is totally off. The instructions show you where to connect the cables too, and the result is the spring and pulleys banging all over the track. The amount of work this is requiring makes the product not worth anywhere near the cost.
I give the product 2 stars because the build quality is good (double spring loops at both ends, nice heavy safety cable with included crimp).

Rated 4 out of 5Â by Almadenreader Weight specification is not accurate
The Everbilt brand extension springs have a 20 LB increment (90, 110, 130, etc.). The 110 LB spring actually has the strength of about 120 LB. The Everbilt 110 LB springs (2-pack) is a great deal if your door weighs about 120 LB. But if your door is 110 LB or a little lighter, the spring tension is too strong and will always pull the door open. This happens when you test the door manually (the door is disengaged from the automatic door opener). If the spring tension is too strong compared to the door weight, adjusting the pulley cable length won't solve the problem, because when the door is closed the two springs are extended fully and will pull the door with the full force (120 LB). If the door is lighter than 120 LB, it will be pulled open. If the door is much lighter than 120 LB, it will go up rather quickly.
I really needed a spring with 110 LB strength (no more), so I had to find a different brand that makes springs in 10 LB increments, and the 110 LB model of this other brand worked better with my 110 LB door.
