This is the perfect commercial grade belt swing and chain combination for school, park, and day care installations. For backyard swing set builders that want commercial-grade strength and durability, this is the swing to get. This 6" wide molded swing seat is by far our most popular commercial swing seat. It is a tough swing with high carbon steel spring inserts for strength and to help resist vandalism. Unlike other similar seats you will find on other websites, the triangle hardware is a very smooth coated galvanization. The swing comes assembled to our 3/16" diameter chain which is partially coated in plastisol for a soft grip and reduced pinching.
