For lightweight and budget-friendly pulleys, the A2020P plain bearing single block is ideal for take-up systems or those that do not require friction reduction. For maximum performance, consider the Dynamic block range instead. This plain bearing block is made from recycled plastics and features a durable acetal sheave that rotates on a central axle. Use the included P-Clip accessory for easy fixing to any surface, and utilize the central hole or "becket" as a tying-off point.
