With all of the limited information about rear ramp door cables for your trailer on the Internet, finding out what type you need can be a hassle.
Trust that the experts here at Camco Wheel & Axle won’t lead you astray, as their knowledge of trailer accessories is only surpassed by their ability to install them.
What You Need
As with most trailer accessories, the type of cables you will need depend on the type of trailer, job, or cargo – that is to say – its general use.
Each packet of rear ramp door cables comes with two cables that vary in length according to different brands. Most of them are 1/8 inches in diameter, are made of steel, and are braided for extra durability. The truth of the matter is that many come in the same diameter but vary in length.
So to determine what type you need, you’ve simply got to pull out that tape measure.
You’ve Got to do a Little Measuring
First, you’ve got to lower the rear ramp door down and find the hinge pins where the cable would run through on both your rear ramp door and the opening. Once you have determined that, you’ve got to measure the distance between the rear trailer ramp when it is on the floor to the top end of the doorway on the trailer.
Essentially, you are running your tape measure, or whatever else you are using to measure the distance with, diagonally. Whatever the result of your measurement is, you will need to have at least that much length in cable.
The second way involves a little math, so if you are a math wiz, this method is for you. You can start by measuring the height of the doorway with the length of the rear ramp door when opened. For the simplicity of this example, the height of the doorway will be “A” and the length of the rear ramp door will be “B”.
Then, use this formula to get closer to the amount of cable you would require:
(A x A) + (B x B) = C^2
Let’s say that the height of the doorway (A) is 8 feet and the length of the rear ramp door (B) is also 8 feet. You’d plug those into the formula above to find “C” squared, so it would look like this:
(8 x 8) + (8 x 8) = 128^2
Eight times eight is 64, and then you’d simply add them. Then, you would get the square root of the answer 128. That would be 11.31. After that, you would factor in the number of inches the rear ramp door hangs down from the trailer’s level floor. Let’s say you find that it is 8 inches. Then you would add that 8 inches to the 11.4 (rounded up), and you would get an even 12 feet of cable needed.
While the measuring part of this is definitely the easy part, installing it requires an expert hand. Should anyone with little experience try and attack a rear ramp door cable, they could risk serious injury. Because of the tension of the cables, first-timers and inexperienced persons should seek assistance from a professional installer.
Safety Is A Priority!
It bears repeating that serious injuries can be sustained while installing the cable on your rear ramp door. The cables operate under a lot of tension, much like a garage door, and if you slip up, it could cost you dearly.
