For those tough jobs where regular hardware just won't cut it! These JY-MARINE tube thimbles are built from 316 stainless steel - that's the good stuff that stands up to saltwater, chemicals, and harsh weather way better than regular 304 stainless or galvanized steel. What's a thimble do? It protects the eyes of your wire ropes and slings from getting crushed or over-stressed. Basically, it keeps your cables from flattening out and weakening at the connection points. Each thimble fits up to 3/8-inch diameter wire rope perfectly. We're talking serious marine and industrial applications here - think boat rigging, construction, lifting operations, you name it. The tube design provides excellent abrasion protection, meaning your cables last longer and stay safer. Package includes 2 thimbles, so you've got spares for your next project. Whether you're working on docks, in factories, or any heavy-duty situation, these thimbles provide that extra layer of security and durability you need. No more worrying about your rigging failing when you need it most!
