okay so i had a light bulb go off and had a stroke of genious. external port!!! mounting depth is 7.89 on the rl-p fifteen, if i give it 1.61 inches room between the magnet and back wall should i be safe? and is the mounting depth from the bottom of the mounting ring to bottom of magnet? if it is, in that case add .75 to 1.61 and have....2.36 inches of clearance! go me!
