Gate Hinge Straps are a component used for mounting a gate to a wooden post. They should be used in conjunction with Gate Screw Hooks and Gate Bolt Hooks to properly support wood gates. Hinge Straps allow the gate to be lifted up & off Screw Hooks or Bolt Hooks if removal is desired. Use 5/16" bolts to fasten Hinge Strap to gate (sold separately). Use with 1/2" x 4" Screw Hooks or 1/2" x 6" Bolt Hooks to fasten to post.
