These brackets used on 4×4 posts are height adjustable and can be bolted along the sides of your dock where legs are needed. Generally a 4’x10′ dock section has 4 legs on the first section and two dock legs on the next sections. The 4×4 post feet works as a mud pad in soft ground and has a hole to allow the 4×4 post to pass through so it too is height adjustable. We spike the end of the 4×4 posts with a skill saw and drive them into the ground with the 4×4 post driving cap. This helps stabilize the entire dock and anchor it down. The deeper you drive them, the more holding power they have. The 4×4 brace clamps for 4×4 post support are for attaching 2×4 lumber from post to post and these are also height adjustable. Our videos on this page shows how a dock with the 4×4 post support hardware can be installed easily with two people.
