Sheaves & Snatch Blocks

Why snatch blocks and sheaves matter for rigging and rescue

A block is a simple idea that changes everything about how a load moves.

It lets you redirect a rope around a corner, change the direction of pull, or build a system that multiplies your hauling power. A snatch block opens on the side so you can drop a rope in mid-line without threading the end through. Double sheave blocks let you build stronger mechanical advantage systems. For hauling, rigging and rescue, this is how you move heavy loads under control.

Get the block right and a hard haul becomes a manageable one.

How our blocks and pulleys are different

We are an independent height safety specialist, so we stock blocks chosen for real rigging and rescue work, from trusted brands rather than whatever one supplier wants to move.

Every block is rated, with a working load you can check and match to your system. And we will help you choose between single and double sheave, fixed and snatch designs, so you build the right mechanical advantage for the job.

This is gear we rig with ourselves. When you ask which block suits your haul, the answer comes from real systems, not a catalogue.

How to choose the right block for you

1. Snatch or fixed. A snatch block opens to take a rope mid-line, handy for redirects. A fixed block is threaded through the end. Choose for how you rig.
2. Single or double sheave. Single sheave redirects. Double sheave lets you build stronger hauling systems. Match it to the mechanical advantage you need.
3. Rope size. The sheave has to suit your rope diameter to run smoothly and avoid wear.
4. Check the rating. Use a block rated for your load with margin, and confirm it suits your system.

FAQs about Snatch Blocks

What is a snatch block?

A pulley block with a side plate that opens, so you can drop a rope in mid-line rather than threading the end through. It is used to redirect rope and build hauling systems.

What is the difference between a snatch block and a sheave block?

A snatch block opens to take a rope mid-line. A sheave block is the general term for a block with one or more pulley wheels. Many sheave blocks are also snatch blocks.

Single or double sheave, which do I need?

A single sheave redirects a line. A double sheave lets you build systems with more mechanical advantage for heavier hauls. Choose for the pulling power you need.

Are these blocks rated for the load?

Our blocks carry a working load rating. Always work within it and choose a block suited to your system and rope size.
