Sea-Dog Heavy Duty Thimble 1/4 Inch Rope/Wire, 304 Stainless Steel, Part 170006-1

The Sea-Dog Heavy Duty Thimble, part number 170006-1, is a stamped 304 stainless steel fitting designed to protect wire or rope from direct contact with the load it is hoisting. Sized for 1/4 inch line or wire, it sits inside an eye splice to keep the loop from being crushed under tension while reducing chafe and abrasion at the point of contact. This keeps the splice round, distributes load evenly around the bend, and extends the working life of running rigging, lifelines, and other rope or wire assemblies that see repeated load-bearing use aboard a boat.

Because it is built from 304 stainless steel, the thimble resists corrosion in the marine environment, standing up to saltwater spray and washdown without rusting or staining the surrounding line. The heavy duty stamped construction gives it the strength to hold its shape under load, maintaining a consistent eye shape splice after splice. It is a standard hardware item suited to any application calling for a 1/4 inch thimble, including running rigging, lifelines, and general rope or cable terminations, and is available individually carded or in bulk packaging for outfitting multiple lines at once.
