This is a blacksmith forged copper double gun rack. The rack hooks are approximately 1 5/8" and 2 1/4" diameter after being lined with leather, and about 15" long secured with (6) 1/4" lag bolts that are hand forged. These are made from 1/4" X 3/4" steel. If you need additional hooks, add $40.00 per pair. You may contact me at the email on my Contact Me page to additional hooks. Also email me to specify whether you want steel or copper rivets.
