This is our strongest leash! Mountain Dog’s Carabiner Leash is built with a real UIAA certified locking carabiner that will hold over 5000 pounds.
The Carabiner Leash is assembled by hand in the U.S.A. from recycled climbing rope. This leash is made with 10.5 mm thick UIAA certified dynamic rock climbing rope, which is incredibly strong and durable. The loops at either end of the leash are created with industrial aluminum clamps that are applied with a 3 ton compound press.  We cover the clamps with heavy-duty heat shrink tubing for a clean look. All Mountain Dog Leashes come with an unconditional lifetime warranty that even covers chewing, just contact Mountain dog!
