This compact double pulley is a great addition to block - and - tackle systems. It features a large connection hole that can easily fit two carabiners and is suitable for ropes up to 13 mm. The pulley has prusik minding, allowing the self - locking knot to be installed on both sides and wheels. It's equipped with sealed ball bearings, ensuring high efficiency even during intensive use at high speed, with an efficiency of 80%. The body and wheels are made of aluminium alloy, while the axle is stainless steel. It weighs only 155 g. The specs are impressive too, with a max breaking load of 26 kN and a working load limit of 7 kN.
Using this pulley is easy. First, attach the carabiners through the large connection hole. Then, thread your rope up to 13 mm through the pulley. You can install the self - locking knot on both sides and wheels as needed. When using, keep in mind that the max breaking load is 26 kN and the working load limit is 7 kN, so don't exceed these limits. For maintenance, regularly check the sealed ball bearings for any signs of wear. Wipe the pulley with a dry cloth after use to keep it clean. Store it in a dry place to prevent rusting, especially because the axle is made of stainless steel and the body and wheels are of aluminium alloy.
