I have a 7' x 14' enclosed trailer with 3/4" plywood flooring. I picked up some 4.5" x 5" D rings for tie down points. I also got the 1/8" thick backing plates. I have the J&S Chock too

I have to cut a 3 3/8" hole for the recessed D ring area to sit in. Will this setup be strong enough just going through the 3/4" plywood and having the 1/8" steel backing plate attached.. Will be used to trailer a 10 Fatboy when needed. approx 725 lbs

Yea, that will be plenty strong enough. The D-rings don't have a ton of pull or shear on them when you are transporting a bike. The tie downs aren't fully compressing the suspension so there is no hard shock to the rings.

If you are outfitting a 7x14 take a look at E-Track. I fitted out a 7x14 multi-purpose trailer with 5 rows of E-Track (3 on floor, 2 on the walls) with all the rings, etc for about $300.00. Makes using the trailer for anything super easy and really solid.

Thanks, I already got the D rings so I'm gonna install them. A friend is giving me enough E Track that i will be able to install two rows along the walls too.

Thanks again

 

+1 on the E-track , no large holes to cut either.

 

If you place the d rings over the frame beneath the plywood floor you should be able to bolt them through the frame. Position them over the frame and mark your bolt holes. drill the bolt holes, then cut your 3 3/8 hole just through the plywood and then bolt them down.

 

Well, I thought of loosening the floor screws from the cross members and sliding those steel 1/8" back plates over the cross members then bolting down at least two of the bolts through the trailers frame. But... if just through the floor is more than enough strength then I dont wanna do too much overkill.

Another thing is the thickness of these so call 3/4" trailer floors. The thickness of the D ring is 7/8". The lip of the D ring that sits on top the flooring is 1/8" and the backing plate is 1/8" as well. Most 3/4" plywood is actually 23/32". If that's the case the recessed rings could just make it over the frame cross members, as part of the D ring will sit over the top of the cross member frame. If for some strange reason the flooring is not at least 5/8" thick then the D ring will not sit flush inside the trailer.

The trailer is a Bendron Titian, built in Georgia. If you have done you own recessed D ring installation I'd appreciate some feedback on the install and how its working for you.

I had to order the 3 3/8" hole saw online as no one sold that size locally so I won't be doing the install till next weekend.

 

I installed mine exactly as I descibed. I did not use the backer plates as they wouldn't fit under the frame rail on my trailer. I used the front 2 bolt holes through the frame towards the front of the trailer. This is because the stress would be pulling mostly on those 2 holes. The back 2 holes I used large heavy fender washers. I have trailered back and forth to Florida twice with absolutely no problems. As a previous poster said there really is very little strain on the d rings. I use a wheel chock that is very securely bolted through the frame rails, which actually takes most of the weight of the bike. (Note of disclaimer: we winter in Florida and I haul the bike down and ride it all winter down there. We also haul all our necessary clothes and such in the trailer.)

 

sorry

 

Ditto on mounting 2 of the 4 fasteners to a cross frame.

 

I have noted on some "trailering" posts mention of DETACHABLE chocks, I would appreciate any info on how this is done.

I would also like to see a few pictures of installed E Trak, I have 4 5' pieces and not to sure of the location to install, I use my trailer 7x14 for general hauling from time to time.

Thanks
