These spring loaded clips are the easiest way to connect a swing seat to the vertical swing chains. They’re just like a standard carabiner: press the clip in, then hook it through the chain and the seat. Available in 2 sizes: 5/16″ x 3″ (Unit# H160), or 3/8″ x 3-1/2″ (Unit# H165 — add $1.00). The latter is wide enough to fit just about every connection, including swing hangers and grommeted seats. Buy yours online now!!
