Pulley Block for 3/8 in Wire Rope

This Peerless pulley block handles wire rope up to 3/8 in diameter. The single steel sheave measures 4 1/2 in outside diameter with a 19/32 in depth. It is designed for lifting and pulling operations where an upright-mounted block is required.

3/8 in Maximum Cable Size

The compatible rope diameter of 3/8 in is the critical specification that determines fit. The sheave inside diameter of 3 11/32 in and single groove are machined for this specific wire rope size. Using a different diameter will compromise seating and load distribution.

Bolt-On Upright Mount

The block attaches via a bolt-on upright mount with a 9/32 in mounting hole. A sleeve bearing supports the sheave rotation. The steel housing and sheave provide durability for industrial lifting tasks, while the lack of a rated working load limit means the installer must verify capacity against the application requirements.

Questions about this item

What does the 3/8 in maximum cable size mean for actual lifting jobs?

It sets the upper limit for wire rope diameter that can run safely through the single steel sheave without jamming or excessive wear.

How does the bolt-on upright mount limit the way this block can be installed?

The 9/32 in mounting hole and fixed upright orientation require a flat surface and matching hardware, so the block cannot swivel or hang freely.

What clearance do I need around the 4 1/2 in outside diameter sheave to fit the block?

Allow at least the full 4 1/2 in diameter plus the housing width, and ensure the 19/32 in sheave depth clears any adjacent structure.
