There is always regular maintenance on a playground. However, one event is in need of constant replacement of certain parts: swings. The Barrel of 500 feet of 3/16-inch Link Steel Swing Chain is an excellent choice for those that are running regular maintenance on a large number of swings. When ordering by the foot, the chain comes as a set length, but set lengths only work if you use the same type of seats with the same top rail height. Somewhere that has bucket seats and belt seats combined into one set, but seperate bays, might find preordered chain to be tedious. It becomes an even more vexing problem if the different swing sets all have different rail heights. Swing chain, by nature takes regular wear from the innate motion of swinging. And nature itself adds its own two cents with weather than can take a toll over time even on our zinc coated steel chains. Our swing chain combines being affordable, strong and provides you the flexibility to cut to length as needed. Please note: The barrel is not included.
