FAQ
Frequently Asked Questions
No. While all snatch blocks are pulleys, the key difference is the hinged, openable side (the 'gate' or 'cheek') which allows it to be placed on a rope mid-length, unlike a standard block which requires threading the rope's end through it.
Its primary uses are in maritime/boating (sailing rigging), forestry/logging (skidding lines), construction and heavy haulage (recovery and lifting), off-road vehicle recovery, and theatrical rigging.
No. You must match the snatch block's size and rating to the specific type and diameter of rope (wire rope, synthetic fibre, chain) to prevent damage to the rope and catastrophic failure. Using a block designed for wire rope with a soft synthetic line can crush it.
It refers to the action of quickly grabbing or 'snatching' the rope by closing the hinged side of the block around it. This contrasts with the slower process of threading a line through a traditional block from the end.
