Lower Triangulated 4 Link Bracket
Ours are bit different than the rest, improving where we could and of course out of a solid 1/4" material rather than the 3/16" many companies will tell you is enough. I really want to make a point that 3/16" is not enough for this type of bracket. These are right down on the bottom and take serious hits all day. We even add a reinforcement skid to them so they don't wear out from all the dragging over the rocks! We also add front reinforcement's that tie the top to bottom and take the first hit so the rocks do not damage the crossmember.
They are made in a 2 5/8" width to fit all the standard joints, we do not make them smaller because a smaller joint just dosen't belong down there. They have a 9/16" hole but are easily drilled out to a larger size. The Crossmember you use should be a stout piece of tubing, they are cut for 1.75" tube and I would suggest at least 1/4" wall.
