Ronstan's bushings provide chafe protection where lines pass through decks, bulkheads or spars. Bushings with stainless steel liners offer increased abrasion resistance. Low profile versions without mounting screws may be glued or pressed into place. PNP54AC, PNP54B and PNP54C are suitable for mounting on round or curved surfaces, and allow threaded swage terminals for 1/8" and 5/32" wire to pass through.
