This Replacement Dolly is for use with the VPC ADA Easy Stair. Place the "V" of the dolly onto the lower rear edge of the deck adapter, with U-trim visible. Place straps around the front of the handrail sockets and buckle together. Straps on the buckle may have to be readjusted to tighten the dolly firmly to the deck adapter. The dolly should not be able to unhook and slide off of the lower rear corner when properly adjusted. Remove the dolly when the easy stair is placed in the pool for use by swimmers.
