Boat owners, DIYers, and rigging enthusiasts - these stainless steel turnbuckles are seriously heavy-duty! Each M5 size turnbuckle measures 137mm (5.4 inches) total length and can handle a breaking load of 1100 pounds, making them perfect for all kinds of tensioning applications. The closed body design with jaws on both ends gives you secure connections with clevis pins and safety wires that won't let go when you need them most. Made from premium stainless steel, they're highly resistant to rust and corrosion, which is crucial for marine use but also great for outdoor projects where weather resistance matters. Installation is straightforward - just remove the split ring, take out the clevis pin, and connect to your eyes or other hardware. They're fantastic for boat rigging, zip lines, guy wires, fencing, or any project where you need adjustable tensioning. The 2-pack gives you extras for multiple projects or backups. Since they're made from quality materials, you can trust they'll hold up over time without corroding or failing. If you work with ropes, cables, or any kind of rigging that needs precise tension adjustment, having a few of these turnbuckles on hand makes the job so much easier and safer!
