Support or tie-down heavy loads with the help of the heavy-duty carabiner by Trek Proof. Made of a sturdy steel alloy, they're rated to hold up to 4,000 lbs and are resistant to rust. These carabiner clips have a tightening mechanism to keep the gate securely closed, preventing straps or ropes from slipping out. A knur LED texture makes the machine easier to grip when tightening or loosening and allows for one-handed operation. This is a reliable and suitable carabiner for camping when you want to tie down a tent or hoist up a load of gear and keep it off the ground. A storage pouch for holding the carabiners is included.
