This is the dual version of "H-55 Chain Fully Coated 56" ( 1ea )" Since I wanted three coated chains for a tire swing, I ordered one of the H-55X2 and one H-55. Both the chain and coating are of good quality. There were three things I liked about Playkids and these chains. 1. Free USPS priority mail shipping. A found a few other places on the web that had OK prices on the chains, but they wanted way too much money for shipping (I wondered if they had never heard of USPS priority flat rate shipping?). 2. These chains are fully coated (not just partially coated). This is perfect for a tire swing where you might sit down and hold the chains low or stand up on the tire and hold the chains high up. 3. Included quick-links. Each chain came with two quick links. This saved a few dollars and I didn't have to take the chain down to the hardware store to see which quick links would fit.
