Working with 3/16-inch wire rope or cable? You'll need these aluminum swage sleeves to finish the ends or create stop points. This pack gives you 50 sleeves, which is plenty for a few projects. They're made from aluminum, so they're strong but also relatively easy to crimp onto the cable using the proper swaging tool. Once crimped, they create a permanent, secure stop that won't slip. You use them to prevent cable ends from fraying, to create loops with thimbles, or to mark a specific point on a cable run. They're essential for jobs like building railings, setting up guy wires, crafting furniture, or any DIY project involving cable. Remember, you need a crimping tool to install them properly - they don't just slide on. A very handy and inexpensive hardware item to have in your kit.
