The Bow Post replaces the arrow rest bolt on your bow and allows you to attach the bow to a Clamp Lock on your belt or backpack. It is quick and easy to use and makes hiking and glassing far more enjoyable. -Choosing your Bow Post-You will want to use the shortest Bow Post possible. If you have a arrow quiver running parallel with your bow the Bow Post will need to be long enough to protrude past your arrow shafts. Normally requiring a 1.5 or 2 inch Bow Post. If your quiver runs perpendicular or off to one side from your arrow rest bolt then you will need the 1 inch Bow Post. They recommend using the Clamp Lock with Tek-Lok for your belt attachment. It gives better stability over just the Clamp Lock for this application.They also use the Bow Post in conjunction with a Camera Lock to mount their bow to the wall. It helps with organization around the shop. BOW POSTReplaces the arrow rest Bolt5/16-24 ThreadsConnects to Lock familyConnects to Grip On family
