The DEUS "O" is a machined aluminum donut with a deep flange. Use it as a rope termination thimble by tying a barrel knot around the eye, or as a rigging eye to balance and direct loads. As a termination thimble it eliminates chaffing and rope wear caused by a carabiner or other connector while also increasing eye strength by increasing turning diameter. "O"s are reusable. Different sizes for different rope sizes.
