Huh? Maybe I am misunderstanding or maybe it's the apfelgoodness. My banjos have a bolt on the bottom and the larger ones have mounting tabs on the side.
It is a good option but will cost you $24.00 per shield plus shipping (on the plus side, it is stainless steel!). I built 2 shields and pay $5.70 for the material ($2.85 each!). If you have access to a MIG welder, should consider the option!
