Front Clamp gap is 3/4inch. Placement of clamp is on cutting edge of your tractor bucket. Our Clamp is held onto your bucket by drilling a 1/2" hole. Top of Clamp is threaded to except our 1/2" bolt. This bolt goes through from the bottom of Clamp then up through your bucket to be threaded into Clamp. (No wedging bolt from the top. It just won't hold together) Benefits are distance to front tractor tire is greater; closer to your up tilted bucket for getting another tee-post; No restrictions on aligning tee-posts.
