Our 50mm block range are simple yet strong blocks, low weight and operate well under a wide range of load conditions. The use of carbon fibre needle roller bearings means that they run well even under high loads whilst freewheeling under light loads for fast line take-up.The 39.05 has a swivel attachment at the top so that the block can rotate to line up with the direction of pull or load.
