The heavy-duty P-A5 Stainless Steel Chain Set includes industrial-strength chain links made of stainless steel with a zinc galvanized finish, and a super-grade pro-style swivel that allows the heavy bag to move and spin naturally, without any tangling or knotting. The set comes with five chains, two high-strength Spring Hooks, and five professional-grade quick links, which make it easy to attach the chains to larger heavy bags that have five top D-rings. This chain set can be customized to fit heavy bags with 2, 3, 4, or 5 top D-rings, and it is ideal for heavy bags that weigh up to 250 lbs. The set has a length of 29 inches, providing a perfect fit for heavy bags.
