The Allen 30mm Plain Bearing Double Block with Becket is a versatile and durable choice for take up systems or systems that do not require friction reduction. For optimal performance, we recommend our Dynamic block range. Crafted from recycled plastics, this plain bearing block features an acetal sheave that rotates around a central axle for a long lifespan and low maintenance. It also includes an ultra-strap made of stainless steel for a strong and rope-friendly attachment point. With its convenient becket, this block makes tying off easier and helps keep the load centered.
