Very heavy duty spring,would not bolt up to my trailer as is l had to drill 2 holes in each bracket and bolt it on to my existing bracket,this spring is much more thicker and wider in diameter that's why it doesn't bolt up directly but it is a very easy modification.lm a bread man and l have a hallmark edge trailer with and extremely heavy door the spring it comes with works good but they only last about two or so.l don't think l will have to worry about changing the spring for a good long time, based on the size and the way it effortlessly handles the weight of the door.lf you will notice one of these springs way smaller and has a smaller bolt pattern notice on the other photo the ramp door is open anthe spring is barely stressed but the door is very easy to pull down and you can raise it up with one arm.

The coil spring works great. I saw a ramp door online and copied it for my shed. I built the ramp door from the shed double opening doors and used most of the parts from etrailer.com The dual spring is used to assist opening and closing the ramp door. I calculated the weight and called etrailer.com and they helped me size the dual spring.



by:

Great spring for my 4 ft door on a small mc trlr! It arrived w a damaged roller n you quickly sent a replacement! I had a friend who installs garage doors to install it for me and it works perfectly! Thank you! The door was getting a little too heavy for me to safely lift.

Perfect device to making our life easier while closing our snowmobile trailer door. The video on line was excellent, product quality excellent as well. Like always, the shipping was perfect. Install took some time, but we got it done. The price was outstanding as well. We can always count on superior products, service and delivery from etrailer.

  • How To Choose Correct Ramp Door Spring for a Nitro Toy Hauler Trailer
    The Conventional Ramp Door Spring part # CB250D96SHD is designed for a trailer door measuring 80" to 96" wide with a hinged weight up to 250 lbs. In order to confirm fit, you'll first need to measure your door end to end. Then, you'll need to find the hinged weight which is calculated by placing a scale on the ground in the center of the landing path of the door edge (no cables attached). If the weight is between 230-250 lbs per se then this would be a great option for you. If you have...

    The part # CB250D96SHD has a total weight of about 45 lbs. It has a lifting capacity (spring capacity) of 250 lbs. That means it can provide up to 250lbs of lifting assistance depending how you wind it.

  • Would Enclosed Trailer Ramp Spring # CB250D96SHD Be Rated High Enough for 92 x 74 inch Ramp
    The Enclosed Trailer Ramp Heavy Duty Spring - Dual, 96" Wide # CB250D96SHD is rated for doors up to 250 lbs. I'm confident your ramp won't weigh more than that unless you've added weight to it beyond the decking.

  • How to Determine Required Capacity of Trailer Ramp Torsion Spring
    On a hinged trailer ramp the hinges will carry a varying portion of the ramp weight depending on the ramp's position. When fully opened/extended the torsion spring will actually be holding more of the ramp's weight that when it is almost fully raised. In the fully vertical position more of the ramp weight is on the hinges since the ramp will be more directly over them. The M-3 Enclosed Trailer Ramp Spring # CB250D96SHD can lift 250-lbs of ramp weight. You can use a scale to weigh your...

  • Where Is Door Bracket Mounted When Installing Enclosed Trailer Ramp Spring CB250D96SHD
    The # CB250D96SHD is designed to work with trailer ramp doors that open from the top and when fully opened create a ramp used for loading the trailer. The brackets that are attached to the door are typically placed at the top of the door(top of door when closed). The bar that has the springs and drums attached is mounted on the header above the door in the trailer just like a garage door spring assembly. If you are not accustomed to adjusting the springs on a system like the # CB250D96SHD...

  • Can A Second Spring Be Added To A Ramp Door For Easier Operation
    It is possible to add a second spring and this will help some with the added weight but the best option would be to purchase a new dual set. The second spring is really just an additional cable for security. The new dual set allows you to get a higher rated spring which is where you will see the most benefit in helping with the extra weight. Furthermore, unless you know what exact weight spring you have now it would not be possible to order just a single spring. There isn't any sort of...

  • Does Placement Of Cables Change Weight Capacity Of Enclosed Trailer Ramp Spring
    The 250 lb weight capacity of the Enclosed Trailer Ramp Spring, part # CB250D96SHD is for the weight of the ramp and not the tension on the springs. The spring is designed to handle the 250 lb ramp regardless of the placement of the cables, although where you place the cable ends would vary the load and stress on the spring. The installation instructions for this product are recommended for individuals who have experience winding torsion springs. If you have not worked with a torsion...

  • Can a Trailer Ramp Door Spring System Be Used on a 12 x 16 Foot Building
    I do recommend the 96 inch system # CB250D96SHD. You can trim down the length for a better fit. The 250 pound capacity will be enough for your door as long as your maximum weight is correct. The springs are longer than on the shorter systems, as is the main shaft. The actual product weight is going to be slightly different with this system being around 45 lbs. It is also strongly advised to have this system professionally installed by a garage door company because torsion springs can...

  • Distance Between Strap Anchors for M3 Ramp Spring # CB250D96SHD

  • Is M-3 Enclosed Trailer Ramp Spring CB250D96SHD Compatible with 90 x 96-Inch Toy Hauler Ramp/Door
    The M-3 Enclosed Trailer Ramp Spring # CB250D96SHD 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 250-lbs. The main tube is 96-inches long but it can be cut down to as short as 80 inches to fit your trailer width. It comes with mounting brackets to install it to the trailer...

  • When Does the Spring Tighten and Loosen on an Enclosed Trailer Ramp Spring
    On a torsion spring like that on # CB250D96SHD 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.

  • Could the Ramp Spring Part # CB250D96SHD Replace a Smaller Ramp Spring
    The closest ramp spring we have to what you have is the part # CB250D96SHD that you referenced which is slightly larger than your current setup but could still be made to work. It can be cut down to a minimum length of 80 inches. 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 accidentally it would fling tools at high enough velocity to easily kill someone.

  • Can Mounting Brackets be Moved on Enclosed Trailer Ramp Spring
    It is not recommended to adjust any of the parts attached to the main tube of a spring like # CB250D96SHD because of the tension on the springs. Only a certified garage door installer should make adjustments. While it is possible to move the brackets it would be easier to just move the top L-brackets to point out instead of in or just replace them with longer L-brackets to fit the mounts you have.

  • Recommended Ramp Door Spring Assist For A 8 Foot Trailer
    When installing a spring assist on your 8.5 foot wide trailer I recommend The Conventional Ramp Door Spring for 8 foot Wide Enclosed Trailer - Dual Spring - 250-lb Capacity # CB250D96SHD. This will work for you 8-1/2 foot because of where the springs actually mount. This dual-spring setup lets you easily open and close the ramp door on your enclosed trailer and eliminates the risk of it freefalling. It will fit trailer doors between 80 inches to 96 inches wide. It has a sturdy steel construction...

  • 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 # CB250D96SHD. 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.
