The A2020P is our top choice for applications requiring a lightweight, cost-efficient pulley. Plain bearing blocks are perfect for systems that do not need friction reduction or for take up systems. For optimal performance, consider using the Dynamic block range instead. Made from recycled plastics, this plain bearing block is durable and easy to maintain. Built-in swivelling hook allows for easy attachment and removal, while also swiveling to align with changing pulling forces. Please note, the swivel function cannot be locked. The acetal sheave spins on the central axle, providing long lifespan and low maintenance. A stainless steel strap, called Ultra-Strap, securely holds the block together and provides a strong, rope-friendly attachment point. The hole running through the middle of the block can also be used as a tying off point, known as the becket.
