This bracket adjusts the Fish Mate F14's position over your aquarium so it doesn't extend as far over the tank. This can help if the stock glass mounts require you to move your lighting further back in order for it to fit. Simply remove the three rubber feet and slide the post into their places. Insert the stock glass mounts into the holes on the bracket and mount to the tank like normal. It maintains clearance for the airline so you can still run an air pump on the feeder to prevent moisture from clogging the feeder.
