First of all, if it doesn't have to do with computers, I generally suck at it, especially when it comes to cutting, measuring, etc. My brain just doesn't get it. However, wanted to share my experience with this product.Recently bought a nice utility trailer that doesn't have any tie downs. Found this product, seemed superior as it has toggle bolts, etc vs screws. Definitely heavy duty. But one thing it doesn't have is instructions. None. Nothing. Not even Ikea pictures! So I come here and start reading other's reviews. Common theme was cut out as little wood as possible and one person said, you only needed a 3 1/4 hole saw. So that's what I got. That was a bad piece of advice. The support plate may indeed have a 3 1/4 opening but the D-ring, which actually goes in the hole you cut out, is bigger. 3 out of the 4 holes I cut with a 3 1/4 hole saw then spent all kinds of time trying to widen it and I don't have a router so it was a very painful process. Then my bolt holes no longer lined up because my widening process wasn't exactly scientific. Redrilling holes, yada, yada, what a pain. So, do this:1 - Buy a 3 1/2 hole saw2 - Mark out where you want to install them using the plate as a template but check underneath where you plan to install it to make sure nothing is in the way, like a support beam and that the plate will fit where you plan to cut. I had to move to the 2nd board from the outside as the plate wouldn't fit if I used the first board3 - Cut the hole with the 3 1/2 hole saw, the d-ring plate will drop right in. Not the 3 1/4 saw you used based on bad advice. Don't do it.4 - Mark the bolt holes5 - Technically you only need to drill out a 3/8 inch hole for the bolts but probably due to my terrible construction skills, even though the bolts would go through the d-ring fine, I couldn't get the plate holes to line up. So I ended up using a 1/2 drill bit and even then would usually have to widen a hole or two.But that was the easy part, after using a 3 1/2 hole saw. If you want to really waste time, go ahead, use a 3 1/4 hole saw. I'll start the popcorn and enjoy the show....
