Having a broken garage door is never a fun time. It’s never a safe time either. Garage door springs are used to lighten the amount of energy needed to open the garage door. When they’re broken, the user has to do this on their own. This makes opening a single panel garage door extremely difficult. North Shore Commercial Door wants to help eliminate the possibilities for injury or damage by assisting with your repair!
When the springs for your E900-R Residential Single-Piece Garage Door Hardware kit fail come to North Shore Commercial Door. We have a great selection of Lock-End extension springs (SL-Series) to fit your door, and better yet, we’ve made ordering easy!
The SL-Series of springs are an extension spring prepared with a specialty end to fit the E900-R jamb type hardware kit. Lock-End Springs are commonly found on wider Single-Panel Garage Doors (also called One-piece Doors, or California Knee Knocker Doors) that can accommodate two Cars (16 feet wide). The springs connect the jamb hardware kit to an anchor to provide the necessary tension for an easy use application.
Spring set ups come in different shapes and sizes. Prior to ordering it is recommended that you look at your set up to determine the number of springs you need. Common set ups include one spring on each side of the door (smaller doors), or two springs on each side of the door (wider doors). Safety experts recommend that you replace the mounting hardware when replacing the springs. Each side of the door requires one pair of hooks. If you have a single spring on each side you need the 97509800 C-Hook. If you have two springs on each side you need to purchase the CW15 W-Hook.
HOW TO IDENTIFY YOUR SPRING SIZE:
The manufacturer recommends that the cable remain intact on your spring for repair purposes. This is because the part number on the label identifies the type of spring you need. The Part number can be broken down into 3 pieces, for example SL728 will read as SL-7-28. “SL” at the start of the label tells us the type of spring we need, in this case “SL” stands for Lock-End. “7” tells us what size wire is needed to make the spring, for this model it is .177 in #7 Gauge wire. Finally, “28” tells us the over all length of the spring. This model would be a 28 inch Lock-End Spring made from #7 (.177 In) gauge wire.
WHAT IF MY SPRING DOESN’T HAVE A LABEL?
If the label has come off of your spring you can still calculate which spring you need. You just need to measure the outside diameter of the spring, as well as get the wire size. The wire size can be calculated by measuring 10 coils with a ruler, or tape measure, then dividing that number by 10. After that you just need to identify the spring end you have.
