Expert Answers about M-3

  • Recommendation for Enclosed Trailer Ramp Springs for a 7 Foot by 14 Foot Enclosed Trailer
  • The system that will probably work best for you is the Enclosed Trailer Ramp Spring - Dual, 81 Inches Wide, # ERS120D81. I went out to the warehouse and measured the distance between the mounting brackets. It is 64-1/2 inches from bolt hole center on one bracket to bolt hole center on the other bracket. The overall length is 81 inches. Since you have a 7 foot (84 inch) wide trailer, the 81 inch assembly should be a good fit. An assembly that measures 96 inches wide will be too long to...

  • What are the Dimensions of the Enclosed Trailer Ramp Spring ERS120D81
  • You did not mention what specific dimensions you were looking for, so I took several. I then produced a pictured showing the measurements. The blue arrow indicates the center to center distance between the mounting holes. The green arrow is center to center between the drums. The yellow is the space between the spring assemblies. Purple is the length of a spring assembly. The drum is 2-1/2 inches wide, 4-3/8 inches in diameter. THe spring is 2-3/8 inches in diameter (not under tension)....

  • Trailer Ramp Door Is Hard to Open and Close, Do the Torsion Springs Need to Be Replaced
  • It could be that the springs are worn out and need to be replaced with either new springs or a new system such as # ERS160D96. Inspecting, working on, and/or installing these systems is not something you would want to do yourself because they can be dangerous (the springs are under a lot of tension). I recommend having a garage door company take a look at it to determine if anything can be done to fix the existing system or if a new system is needed.

  • Options for Trailer Ramp Lift Springs for Ramps that Weigh 100 lbs
  • If you have an enclosed trailer you could use the part # ERS160D96 as an overhead torsion spring to help lift the ramps. If it's a utility trailer with side rails you could instead use the part # RA-27C as it is designed for helping lift trailer ramps.

  • Availability of Enclosed Trailer Hinge Ramp Springs
  • I do believe we have the springs that you are looking for, but they are not part of a kit. We have a left, # RS16933LH, and a right, # RS16933RH. These springs are for a 1-1/2 inch diameter shaft. They will need to be welded into place with the two arms facing down and flat against the trailer and door surfaces. Each spring is rated for 2,000 pounds torque to help with lifting and lowering ramp doors on trailers.

  • Will Adding Enclosed Trailer Ramp Spring ERS160D96 Double the Lifting Strength of My Trailer Door
  • Adding additional springs like the Enclosed Trailer Ramp Spring, # ERS160D96, will make it much easier to lift the trailer door on your enclosed trailer. However, if you were to add too many springs or too large of a system, the door may not stay down. Also, it is recommended that unless you have experience working with torsion springs, this system should be installed by a professional with torsion spring experience. If you determine that the double spring system is too large, then I...

  • Enclosed Trailer Ramp Dual Spring for 72 Inch Wide Door
  • You can use the 81 inch ramp spring # ERS120D81 if you would like. The springs and pulleys are held in place with set screws, so you can move the springs closer together and tighten the set screws down to keep the springs and the pulleys in place. I spoke with the manufacturer, M-3, and they said that this spring will work well on your 72 inch wide door. M-3 said the spring will work on doors down to 62 inches wide. You will want to position the pulleys as far apart as possible without...

  • Overhead Clearance Necessary to Install Enclosed Trailer Ramp Spring # ERS160D96
  • According to our friends at Redneck Trailer Supply, the reel on the end of the Enclosed Trailer Ramp Spring, # ERS160D96 measures 5 inches in diameter, so you would need a bit more than 5 inches of room on the header above the rear door of your snowmobile trailer.

  • How to Pick Out Replacement Cable Length for Trailer Torsion Ramp Spring
  • You would want to measure from the bottom of the ramp door all the way up to the spring above the door frame when it is open to determine the minimum length cable you would need for your spring.

  • Can 81-Inch Enclosed Trailer Ramp Spring # ERS120D81 Be Cut Down in Length
  • According to my contact at Redneck Trailer Supply the M-3 Enclosed Trailer Ramp Spring # ERS120D81 can be cut down to a reduced length. We also offer a 66-inch single-spring version, part # ERS80S66, which has an 80-lb capacity. Both kits include all hardware necessary for installation except for mounting bolts which you will supply.

  • Can the 96 Inch Wide Enclosed Trailer Ramp Spring be Trimmed to Fit a 92 Inch Wide Trailer
  • Yes you can cut the shaft on the 96 inch wide ramp spring, # ERS160D96, to fit your 92 inch wide trailer. The shaft is made of steel tubing so the proper saw or power saw blade would cut through it. Be sure to get a straight cut and file down the rough spots. Regarding installation, a professional with experience should install this in your trailer. Torsion springs are under a lot of tension and can be dangerous if you do not have experience with them. A garage door installer would be...

  • Could # ERS80S66 Ramp Door Spring Be Cut Down for Use on a 5 ft Wide Enclosed Trailer
  • The whole assembly (96 inches wide) would be too long to trim down and still fit. I'd recommend going with a single spring like # ERS80S66, whch can be trimmed down to 45 inches long. The spring has a capacity of 80 lbs. If that's not enough capacity you could use two of them in tandem with one mounted above the other on the door header. We strongly recommend having a professional overhead door technician install the spring for you. The spring needs to be tensioned, and if it lets loose...

  • Recommended Ramp Door Spring for 6x12 Enclosed Trailer
  • When selecting ramp springs for a trailer ramp, you will want to know the diameter of your hinge pin and how much space you have available in the hinge. A typical enclosed trailer ramp uses 3/4 inch hinge pins and would require two ramp springs with a 3/4 inch inner diameter. The ramp springs that we carry fit 1-1/2 inch diameter hinge pins and are designed for use with heavy-duty steel ramps like those on equipment trailers or car haulers. The spring slips over the hinge pin and requires...

  • Recommended Ramp Door Spring for 8 Foot Wide Enclosed Trailer
  • You'll want to choose a spring that's the same width as the ramp door. I'm afraid that the # ERS120D81 you mentioned would be too narrow. You'd want to use # ERS160D96, which is 96 inches wide. You'll have to take about 2 inches off each side of the pipe, but this would be your best bet. We HIGHLY recommend having the spring installed by somebody who's experienced with torsion springs. Tensioning the spring is a dangerous job that shouldn't be undertaken by somebody who's not familiar...

  • Trailer Ramp Spring Recommendation for a 66 Inch Wide Door
  • As you mentioned, we do offer the Enclosed Trailer Ramp Spring - 81 Inch Wide, # ERS120D81. This ramp spring needs a minimum of 56 inches in order for the drums and cables to wind properly. With your rear ramp door being 66 inches wide, this ramp spring would work for your trailer. The weight capacity is 120 pounds. I pulled the Enclosed Trailer Ramp Spring - 96 Inch, # ERS160D96, from our warehouse and also spoke with my contact at M-3 to see if there was any way that this would work...

  • Replacement Cables for Enclosed Trailer Ramp Torsion Springs
  • The Enclosed Trailer Ramp Spring # CAB1-8CB150 that you referenced has a specific application on the Enclosed Trailer Ramp Spring # ERS160D96. This cable is 1/8-inch x 12-1/2-feet long so for applications requiring a shorter cable you can cut it and apply new metal stops on the new ends. This is the only ramp spring cable we offer at this time and it is sold as a set of two. This product is recommended for individuals who have experience winding torsion springs. If you have not worked...

  • Can a Trailer Ramp Door Spring System Be Used on a 12 x 16 Foot Building
  • I do recommend the 96 inch system # ERS160D96. You can trim down the length some on each end for a better fit. The 160 pound capacity though is still under the approximate 200-250 pounds of your door so adding something to supplement this system would be needed to avoid damage to the system. The springs are longer than on the shorter systems, as is the main shaft. The actual product weight is going to be slightly different but the shipping weight is the same. It is also strongly advised...

  • Adjustability of Enclosed Trailer Ramp Spring
  • I spoke with my contact at M-3 who said the ramp spring shaft can be cut down to a maximum of 62 inches and you would still have room to wind the springs. The shaft is made of steel tubing so the proper saw or power saw blade would cut through it. Be sure to get a straight cut and file down the rough spots. The installation instructions for this product are recommended for individuals who have experience winding torsion springs. If you have not worked with a torsion spring system before,...

  • When Does the Spring Tighten and Loosen on an Enclosed Trailer Ramp Spring
  • On a torsion spring like that on # ERS160D96 when the door is opening downward the line is spooling out and the spring will get tighter. When the line is spooling in, closing the door, the spring will relax or get looser. As such if you have not worked with torsion springs before we strongly recommend having a professional perform the installation. A local over head door company should be able to help.

  • Would this work on an 84 wide ramp door in a 96 wide trailer?
  • I spoke with my contact at Redneck about the Enclosed Trailer Ramp Spring, part # ERS160D96 on your trailer. They told me that the pipe that the springs and cable assemblies are attached to can be cut down to work on your 84 inch door. If you decide you want the shorter ramp spring for enclosed trailers that part # is ERS120D81. The installation instructions for this product are recommended for individuals who have experience winding torsion springs. If you have not worked with...

  • The M-3 Enclosed Trailer Ramp Spring # ERS160D96 uses cables that will be plenty long for your application on a ramp door that is 90-inches wide x 96-inches tall. That is precisely the type of trailer installation for which this item is intended. It will work for you so long as the ramp does not weigh more than 160-lbs. The main tube is 96-inches long but it can be cut down to fit your trailer width. It comes with mounting brackets to install it to the trailer header but hardware is...
