The two blocks of this pair are made of a black epoxy steel frame and a hook with a safety latch, as well as three rollers with a diameter of 45 mm made of forged steel.
One of these two Lyonnais rope blocks has a ring that allows you to attach the rope.
The groove of the mounted rollers is 10 mm, which is perfectly suitable for a rope of equivalent diameter.
The blocks are used for hauling loads without height or distance limits. In fact, the limit is determined by the length of the rope used. One block allows for the lifting of a load of less than 150 kg, with a multiplied pulling effort. For every 1 kg provided, you will lift 6 kg vertically!
