  • Nice looking thick brackets.
Size: 4x3.5 inch ( 4 Pack )
These brackets worked very well for building a railing on my son's deck. Good quality and thicker metal than I expected.

  • Strong Well-Made Braces with a High Quality Finish.
Size: 2x4 inch ( 4 Pack )
These are very nice strong well-made braces and at a fair price. I only needed one but couldn’t find any like this without buying a package. Here is the deal, I needed to add a hitch to the back of my yard tractor. I simply drilled out the center hole so that the clevis pin would fit then using a small flat piece of steel as a backing and 2 bolts, I bolted it to the rear deck. No welding and it works just perfectly. Nice heave-duty trailer hitch on the back of by lawnmower. As you can see in the photo, it has already seen a lot of use and no bends or kinks. Like I said, very strong brace. ... show more
