Recessed D-Ring 6,000 lb. Cap. Tiedown Anchors w/Backing Plate - 2 Pack

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.

Really nice, heavy duty D-rings. I purchased the 4 pack and later ordered a 2 pack. Installation is much easier with two people, where one can work above the floor and the other below. With my son and I working as a team, it took less than 15 minutes to install each one. We used a different method to install them, rather than the instructions. You will definitely appreciate the backing plates, as there is minimal material between where the large hole is cut (you will need a large hole saw and good size 1/2 drill) and the mounting bolt holes are drilled. I used 3/8" carriage bolts, 1 3/4" long to attach to the 3/4" plywood floor of my utility trailer.

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.

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 D-rings with backing plates are a bit of a compromise since these plates don't really lend themselves to being welded in as they should. You certainly could weld them but that's best done during the trailer construction process and is a little tougher once it's complete. Anyhow, quality is good and I'm happy with them. The D-ring hole in the backing plate is not right in the middle so it gives you a few options for the arrangement of your install.

This is a quality product. Buying the 12 pack was hands down the best price I could find. Of course if you don't need 12 then why buy this many but I needed them all and they worked perfectly. I used a 3.5" hole drill and slightly eared out the edges to allow the hook hardware to slip in the whole properly. I used a router bit on a drill to do this step which worked great. You end up with a mickey mouse type look for the hole with the ears at the 10 and 2 positions on the clock. Heavy duty tie down and the backing plates are a perfect fit.

Excellent D-Rings, installed in our 8.5 x 16 enclosed trailer. I bought D-rings just like this from the trailer dealer that did not come with bottom plates and were more expensive than these. So I found these on Amazon and please to see the plates included--which are needed to have the 6,000LB tie-down capacity. There are no bolts included, which is known when you purchase, so that's not a reason to down-grade the item. I went to HD and purchased the 3/8" x 1 1/2"L bolts, flat & lock washers, and nuts. Motorcycle tires roll right over them with no issues. Super product!

Great product
