This hanger is designed specifically for our Precision Rifle Rack. It is constructed of a single piece of steel tube that has been cut to accept 1/2" hardware.Use this in conjunction with any of our Precision Rifle Rack targets to configure your own complete target system.Minor assembly is required with this product. All of our stands and hangers are designed to accept 1/2" hardware (included) which will require you to use power or hand tools to tighten. Wrench/socket size for 1/2" hardware is 3/4", adjustable wrenches may be used as well. All stands will require two tools (one to hold the nut, one to tighten the bolt), while hangers will only require a single tool as the shoulder of the carriage bolt will lock into place via the cutout on the target.
