N-411-B Western Standard Steel Blocks
|
Blocks for Synthetic Fiber Rope with loose swivel hooks |
- These blocks are built to carry the increased loads of synthetic fiber ropes.
- All hooks are heat-treated alloy steel.
- You can now use a smaller size rope, and in turn, a smaller block, providing capacities which were previously not possible.
