These shackles take the place of S-hooks and need the wrench, H175, to open and close. This head makes removal, because of vandalism, more difficult. These are used when a wide opening is needed. The overall length is 3 9/16". The bolts are 3/8" in diameter. The inside of the smaller opening is ½" across and the larger opening is 1 3/16". Unlike S-hooks they can be used multiple times. They are also much easier to install then S-hooks and much stronger. Some cities and parks are requiring their use instead of S-hooks. Use with our swing hangers, Tire Swing and chain except the C125 green, C127 red and the C128. The shackle is 212 HBS and the bolt is 176 HBS.

**Installation, Safe Use and Maintenance Instructions**
IMPORTANT: Please read for important information. In this material we have tried to provide some requirements stated in the CPSC Handbooks, ASTM F2373-11, F1487-11 and F1148-09. However, we in no way intend for this to be a complete list of requirements. Also these publications are updated frequently with changes therefore, you should read these publications yourself to determine if any part or installation could prove a danger to a child.
To help keep children safe from harm, review installation and maintenance instructions before installing equipment. You can see this PDF.
Installation: Make sure you are using correct size of shackle. The shackle should not crimp material producing a wear spot on whatever material you are attaching to shackle. Unscrew both shackle bolts from one side of shackle body with H175 wrench. Place the large bolt through the widest opening present on one of the components you are attaching together. Place the smaller bolt through the narrowest opening present on the other component you are attaching together. Screw shackle bolt back into shackle body. Shackles can be used in various assemblies. Shackles should never be pulled at an angle because the capacity will be tremendously reduced. Centralize whatever is being attached on the bolt with suitable washers or spacers. Ensure the bolt is correctly screwed into the shackle eye with an H175 wrench. Check that the threads are fully engaged with the body, but not so tight that it causes the body to bend in or that the threads go past the body by more than two threads.
Safe Use: This is for children 0 - 12 years old only. Adults should supervise children at all times. Do not allow children to use unsafely. Do not allow it to be used if damaged.
Maintenance: Do the following to reduce the chance of serious injuries. At beginning and end of each play season and once a month during play season, check for sharp edges and/or cracks in metal. Check for excessive wear. Check for rust and to make sure bolt is still tight and not more than 10% worn. Replace parts as necessary for safety. The shackle bolt should never be replaced with a regular bolt. Maintain detailed inspection and maintenance records for public-use playground equipment.
