An overseas residential half bucket with attached black nylon webbed safety strap and plastic connection and galvanized hardware. The dimensions of the seat are 12” diameter, 8.5” depth and the back holes are 5.5” in length. Our seats have galvanized steel triangles and steel plates that are riveted to the seat with galvanized rivets. We go to the added expense of welding each triangle together so they cannot be pulled apart and pulled off the seat. We believe our swings are one of the few that have these welded triangles. The triangle is constructed of 3/8” dia. cold rolled steel with the ends welded together. The plate is 1/16” thick h.r. stamped galvanized steel. The rivets which are used to rivet the plate through the EPDM rubber and steel insert are made of ¼” diameter steel. There are three rivets on each side of the seat. The A1003 high back tot seat has a 1075 steel insert, full hard, painted with a non-rusting adhesive, and then coated with rubber that is from ¼” to 3/8” thick. The seat should last 2 years in harsh conditions and up to 5 years in optimal conditions. Some conditions may require replacement sooner. Tensile strength1200 lbs.
