Commercial quality large end S-hooks are designed to fasten chain to swing hangers and swing seats to help prevent binding.  Holds up to 750 lbs. They are plated to help resist rust.  S-hooks that are not bought from a playground manufacturer do not have the quality control and have been known to break with the first “swinger”.   

Installation:  Make sure the S-hooks are closed to within .04 to meet ASTM safety standards.  To do this you will need to use our S-hook pliers or a regular pair of channel lock pliers.    

WARNING: Once the S-hooks have been opened they will have to be replaced to avoid injuries from coming open and/or breaking.  Make sure that if you are using shackles they are also tightened.     

Safe Use:  This is for children 5-12 year olds only.  Not for Adults.   Adults should supervise children at all times.  Do not allow children to stand on or use unsafely.  Do not allow it to be used if damaged.
