These popular ratchet blocks will grip loaded hauling lines to relieve the operator of much of the strain.
The design of the sheave is such that when the rope is easdd off it will slide around the sheave without the sheave turning, hence a hefty lantern can be lifted and held in place without having to hold the full weight.
These blocks do NOT lock the rope so the load can be gently lowered against the fixed sheave.
The Set screw in the three-way head allows the head to be fixed parallel, at right angles or to freely swivel.
