Do you want to install D-rings in your trailer? If you want to know how-to install D-Rings, then it is best to read this easy step-by-step guide on how-to install D-rings in a trailer.
What is a D-Ring?
D-Ring, as the name suggests, is a 'D' shaped piece of cargo securing hardware that is either mounted directly to the surface of a trailer or secured to a D-ring tie-down strap. It enables the user to customize his trailer's configuration with load-specific trailer tie-down anchors. That is why D-rings are also called Ring Anchors.
Check the stamping on the plate before you buy. A common recessed pan D-ring is stamped with a 1,665 lb safe working load and a 5,000 lb minimum breaking load, which is the same ring at a 3 to 1 design factor. Rate your tie-down points off the safe working load, not the breaking load, and use enough of them for the load you are hauling.
The working of D-ring is quite simple. All you have to do is to pull it up in an upright position so that you can hook a tie-down with it. When you are not using it, simply push it back so that it gets leveled down with the floor.
Installing D-rings in a Trailer
Step 1: Choose the best location in your trailer to mount your new D-ring tie-down. Just check the underneath of your trailer to ensure that there isn't anything in the way that won't allow you to put the backing plate underneath or to drill a hole.
Step 2: Measure the exact location on which you are going to have d ring installed.
Step 3: Take a pilot bit on a hole saw (hole cutter) and drill down before the hole saw is used to cut the hole (it is recommended to use 3-1/4 inch hole saw).
Step 4: If the trailer floor is made of plywood, you could drill all the way through. If you do not want to do it, then you can simply drill halfway through the board. Once you are done with it, the center section should be chiseled out before you start drilling holes.
Step 5: Once you have 3-1/4 inch hole drilled, set D-ring's top half into the hollowed place.
Step 6: You'll notice that each side of the hole is hitting the bolt that holds the actual loop in place. Remove a little bit of all parts that are hitting the bolt. As a result of it, you'll see that D-ring's top section will drop down flat with the surface.
Step 7: Mark out holes from the top section of D-ring to drill them and to put bolts through them. Use suitable bolts along with nuts and lock washers to be used on the underside.
Step 8: Put your backing plate underneath the trailer and make sure that it is lined up with the holes you just drilled. Put two or three bolts in it to keep it in place. Put lock washers and nuts on each bolt. Now that all the hard work is done, simply tighten the bolts, and there you have it- a perfectly installed D-ring in your trailer.
The Bottom Line for You
Needless to say, when there is talk about vehicle recovery or anything related to it, the importance of D-rings cannot be neglected or underestimated. Installing D-ring in a trailer is not that much difficult. However, you have to make sure that the measurements are taken correctly to avoid any unnecessary damage to the trailer floor. This guide applies to almost all types of D-rings. If you prefer a service professional install your D-rings, contact NC Trailers for a service appointment.
