If you have a 20# or 50# CO2 tank that needs to be mounted into the back of your truck or inside your trailer this is the bracket for you. Made of 3/16" thick aluminum, this bracket is very secure and strong enough to hold a 50 lb. CO2 tank firmly to a team support trailer wall. It utilizes two stainless steel straps with fine thread turn-buckle latches to hold your tank into the frame. Thick rubber trim keeps the tank from sliding or vibrating against the metal frame. Fits any tank with an 8" diameter.
