These document holders, also called manual canisters and tool tubes, are perfect for when you want something stored safely and close at hand - on trucks, trailers, farm equipment, motorcycles, ATVs, you name it - this tube document holder will keep it safe and sound, away from the elements. Both the cap and the body are made from molded HDPE, which is a sturdy, durable form of plastic, and the threaded screw-on cap has a neoprene seal for added protection. This is the small version of this document holder, measuring approximately 12-1/2" long with a 2" inner diameter. Two brackets, part of the molded plastic body, extend from the bottom of the tube for mounting purposes (hardware not included).
