Unlike traditional saddle style fence brackets that attach a 2" x 4" fence rail to a 4" x 4" wood post, you will love the revolutionary blind connection that OZCO's "EZ-Hide" wood to wood fence brackets provide. For installation, mount the bracket to the post using the included screws. Then pre-drill a 3/8" hole on the bottom of the rail. Tap the rail into place and finalize by installing a 2-1/2" screw. The entire fence rail can be easily removed if necessary by extracting the rail screws and lifting the entire fence section off the brackets.
