Hello John,
We have two bracket kits depending on which cabinet you purchased. Also, if you purchased a wall gearbox, the bracket comes with unit, and is not necessarily the same bracket that comes in the kits. Please contact the Gladiator Pros with the model number of your cabinet and we'll see if we can get this resloved. 866-342-4089. We are available Mon - Fri, 8am - 6pm EST.
