Block 50mm single swivel - Tersma

Tersma Sailing Products

Plain Bearing Blocks are engineered for lightweight, strength, and superior handling. We use stiff glass fiber reinforced nylon to provide metal-like strength, self-lubricant sheave reduces friction and increase efficiency to control the line and 316 stainless steel plain bearing to provide smooth rotation. Plain Bearing blocks give sailors easier power transfer and less wear on rope.
