Feature Review Conventional Ramp Door Spring for 7' Wide Enclosed Trailer Video

The instructions for the Conventional Ramp Door Spring #M374FR state to wind the spring 38 quarter turns or 9-1/2 full turns. At this point you will want to test the door operation and make 1/4 turn adjustments adding tension or removing tension to…

The spring with the black cable drum should always be mounted to your LEFT, standing on the inside of the trailer looking out. This is very important for proper operation. Dual spring systems, like #ERS160D96, have a red-coned and a black-coned…

With your over head garage door springs frequently breaking you may not have the correct capacity springs for your door. We have kits that range from 80LBS #M374FR up to 250LBS #CB250D96SHD. The weight rating is not the door weight but the amount of…

Heavy duty ramp springs #RS16933RH and #RS16933LH install on the hinge of the ramp. I have included a picture of what this looks like for you. Not all trailers are exactly the same but this should give you a general idea of how the springs install.

I checked with M-3 and when you are ready to wind the spring on the Enclosed Trailer Ramp Spring #ERS120D81 you will need to use two 1/2 inch diameter bars (of around 18 inches long). You will insert the first bar into the winding cone of the spring…

Hey Lou, so the install of the Conventional Ramp Door Spring part #362SA7218 is something that should be done by someone who has experience winding garage springs. The amount of turns or preload will be the amount that gives you the correct amount of…

We don't offer an 8500 lb rated surge coupler, but we might have options that would work for you. If the GVWR (weight of trailer plug boat) is 8000 lbs or less, I'd recommend the Demco item #DM8669113 if your trailer has disc brakes or item…

Hello Tim, I am happy to get you into the right spring, but we need to know the weight of the door. You mentioned that the one you are replacing is "orange coded" but the issue is that there is not a real standard and companies use…

I'd go with a double spring personally, Scott. These are typically going to be used on more heavy duty applications like your enclosed trailer with a pretty heavy door. In order to get a proper replacement though, you'd need measure the width…

On a 7 pin round which is the common connection on a semi trailer, the clearance/marker lights are at the 10 o clock position when you look at the trailer wiring connection. When looking at the connector on the back of the truck, that will put the…
