Connect tire swings, oversized chains, and more with the H-Shackle - H172. Designed to connect larger pieces to smaller, one shackle is large while the other is smaller. This is particularly effective for when a chain is larger than the swing seat or vice versa. For tire swings, this is only way to connect the tire to the chains. The H-Shackle - H172 is galvanized steel to stand up against harsh weather for years of use.
For an even stronger version of this shackle, be sure to check out the H-Shackle Stainless Steel - H173.
