Stainless Steel Pulley Blocks

Shop stainless steel pulley blocks for marine rigging, rope handling, wire-rope routing and industrial systems. This collection includes compact and budget blocks, single and twin swivel blocks, swivel-eye and square blocks, surface-mount designs, seine blocks and opening snatch blocks.

Start with the line being carried. Rope and wire rope require a compatible sheave groove, diameter range and construction. Then choose the attachment and body geometry: swivel, eye and hook connections allow different installation arrangements, while Type A, L and U surface-mount blocks provide distinct fastener patterns and line-entry angles. The collection includes both 304 and 316 stainless families, with 316 normally preferred for aggressive saltwater exposure.

Use the Stainless Steel Pulley Block Finder below to compare all 30 grouped families and specialty products by grade, construction, line type and attachment. Open the product page to confirm sheave diameter, line capacity, mounting dimensions, working load and service restrictions. Do not assume that a block is approved for overhead lifting, personnel support or life-safety service unless its published documentation expressly permits that application.
