Quoted from Concretehardt:make sure to get all 3 Cliffy protectors for the shooter lane that way it will be bulletproof
Why come the odd mounting of the shooter lane protector?
Generally you just unscrew the bubble level and slide it up so the lower screw goes where the upper screw used to, then make a new hole to screw in the top of the level. The old lower hole for the level is for the upper hole in the protector. Screw in lower hole of protector making second new hole. Then the level isn't sitting on top of the protector, and all holes are being used.
Maybe you know something I don't?
