Steel cylinders are heavy and cumbersome to carry, but the air capacity and buoyancy characteristics are very desirable for the serious diver. Being able to easily transport these cylinders is a plus. XS Scuba's Steel Cylinder Carry Handle can make transporting the cylinder easy and comfortable. Handle is made from tough and durable injection-molded plastic material with a fold-down handle when not in use. Steel cylinder handle fits XS Scuba Worthington & Faber Steel Cylinders (except Worthington LP77).
