Will this 120 lb spring set handle a 7' x 8' wooden door or a vinyl door?

Asked by: rogmid
My door is 7x9 wood and weighs 120 lbs. If you clamp the cables to the door tracks and use some pry bars and 2x4s you can lift it up onto a bathroom scale. Then you will know for sure what it weighs.

Replace both springs?

One spring broke. Do I need to replace both sides or can I replace one spring?
Asked by: Garageguy
Thank you for your inquiry reguarding this item from Prime-Line Products. You can replace the broken one only but it might cause you more problems. Your garage door can become out of balance, The tension on the order one might not be as good as the new one which will cause the old one to possibly break. We recomend to replace both springs.

will this sprig handled a 7 by 16 ft overhead door.

up & down
Asked by: yarddog
Thank you for your recent inquiry regarding these garage door springs from Prime-Line Products. If your garage door is an old-style “Cantilever” type door; a door that is one solid panel that cantilevers up and out of the way… we do not have any cantilever garage door springs. If it is the newer sectional type garage door and the door weighs about 120 lbs., then a 120 lb. spring on each side will work. How to weigh a garage door: A garage door may be weighed by using a bathroom scale, as long as the door weighs less than 300 pounds. Open the garage door to its full open position. Block both bottom rollers in the track with two “C” Clamps or locking pliers. Release spring tension by disconnecting cable at overhead support bar on both sides. Remove the “C” Clamps (or pliers) and allow door to lower onto the scale. Heavy doors may require two people to lower. (EXAMPLE: a 150 pound door needs two (2) 150 pound springs; one on each side.)

Rated 5 out of 5 by from Installation Very easy to install. The only complaint I have, is that a template was supplied to locate the holes in the wall to hold the mounting strip, and another to locate the holes in the cabinet above, to hold the microwave up. The instructions said to trim 1/16 of an inch off the templates, all the way around, on a dotted line. Why not just provide a template that doesn't need trimmed???
