The d-rings have square holes punched for receiving carriage bolts, providing a smooth and relatively trip free surface. When in use the ring portion raises for application and lies down when not in use, thus creating a flush surface. It is plenty strong and is able to receive multiple tie-down straps simultaneously. **RATED CAPACITY: Also known as "assembly capacity" or "break strength" is the minimum load a complete assembly can withstand before failure in a laboratory pull test when the product is NEW. WORKING LOAD LIMIT: The maximum load weight a tie-down should be subjected to during normal use. To assist in making the proper tie-down choice the Federal D.O.T. requires the W.L.L. to be 1/3 of the Rated Capacity. BACKING PLATE SPECIFICATIONS: 1) The backing plate measures 6-1/2" x 6-1/2". 2) Thickness is 11 gauge (a little thinner than 1/8). 3/8" holes. 3) 3-1/2" diameter cutout. 4) Steel backing plate is zinc coated to inhibit corrosion. INSTALLATION - these D-rings require routing, or cutting a hole in the floor. We recommend creating/cutting a template and then transferring to the desired location. If you use a 3-1/2" hole saw, the d-ring will fit without any further work. Better fit - use a 2-3/4" hole saw then jigsaw the flat edge and then bevel the edge with a wood hasp to create a snug fit.

I was very pleased with the quick shipping
The tie downs arrived in short order. I was very pleased with the quick shipping, packing and overall quality of the tie downs. I mounted them in my utility trailer. I made a template from 3/4" wood stock and drilled a 3 1/2" hole with a hole saw and drill press. The template butted up against the bottom rail of the utility trailer. I used a straight cut router bit 1/2" wide with a flush bearing at the top and set 1" deep; however, I made two passes; first pass at 1/2 inch and the second pass at 1". I located the template with the template hole centered and template butted up against the bottom rail of the trailer. I used a staple gun with 2" staples and tacked the template in place. It held very well and easy to pop out and move to the next location. I drilled a 1" deep starter hole for the router bit with a 3/4" forstner bit flush against the inside edge of the template hole. I set the router bit to 1/2" depth and dropped it into the starter hole with bearing flush against the edge of the template and ran around the outside edge cutting the perimeter. Then I nibbled away at the remainder and slowly cut out the interior of the recessed hole. I lowered the bit to 1" for the second pass doing the same. My son got a kick out of holding the vacuum hose for the dust collector sucking up the debris as I routed. I drilled a quarter inch hole in the middle of the cut out through the remainder of the wood floor and used a counter sink bit to make a funnel shape. This is for drainage should water or moisture get between the bottom of the tie down and the cut out. I sealed the wood, let it dry for a day, then drilled my bolt holes and used clear silicone to seal the tie down and bolts to keep water from penetrating beneath the tie down, and dropped in the bolts and tightened them up. I used 3/8" x 2 1/2" carriage bolts, washers, lock washers and nuts of course. The mounting of the tie downs went perfectly and they give me significant utility. The most important thing to me though is the fast shipping and excellent packing of the product from Mackie Ent Inc (I bought four tie downs with backing plates). As a footnote, I found tie downs at Home Depot. The Home Depot tie downs were half the capacity and cost twice as much with no backing plates. Mackie Ent Inc is offering excellent value and excellent customer service.

Cut right takes time done w/care very sturdy good floor, they hold my ultra classic limited fine.
Not the easiest to install, but worth doing right! A hammer, chisel, jigsaw ,a drill and a paper template of the upper D ring piece makes fora firm fit. You have to get the bolts and nuts to the thickness of the floor.

These are impressively strong and very nice that they drop out of the way
These are impressively strong and very nice that they drop out of the way. I have an 8' x 5' trailer with plywood deck these were installed on and the hardest part was finding stainless bolts etc, and an appropriately sized hole saw that didn't break the bank. I ended up using the backer plate as a template, marked the deck and used a saber saw. The backer plate was also great for drill guide for bolt holes!.Just be sure there's no interference with struts or wires under where you'd like to put these anchors, I thought of that just before making a big mistake, thankfully. The taller edge of the backer goes on the hinge side as pictured, and the loop goes in the direction of anticipated strap tension direction for best strength.There are weep holes in the ring wells to let water out! Nice touch.I haven't needed to trailer my bike yet, but have moved the riding lawnmower many many times over hundreds of miles (get yourself ratchet straps, buy once and be happy ever after) without problems. Some wood preservative (used up some Cuprinol) in the holes and cuts should help keep the deck from suffering the cuts.

Great product but installment don’t come with nuts or bolts a pain
These are great but they take a bit to install. For me had to jack up the trailer and get under it to bolt them on properly. I had to drill a hole in the trailer floor so it sat flush. Not a problem just takes some time to install them. Once they are in you will be very happy with the product. I put these in for added tie downs in my Motorcycle trailer. Oh and they don’t come with the nuts and bolts in the picture

DOES NOT CONTAIN COACH BOLTS FOR MOUNTING
It would be nice to know that they do not contain the bolts to mount them as we now have to go to the local hardware supplier to get bolts so we might as well got the tiedowns from them as well rather than waiting for them to be delivered. The picture also show bolts so would assume they came with them. Why not state it in the listing that they DO NOT?
