This is a listing for a 3 piece padded rail set for a hard sided waterbed. These are the Jumbo rail caps and feature a hard frame that doesn’t warp or break. These have 2 inch foam and are the standard cap size just more foam and Krinkle . They are 82.5-83 inches long to account for your headboard brackets. To install these just put the foot rail on first and then install the side rails so the line up at the mitered corners. These are built to order and usually ship FED EX or UPS in about a week.
Don’t forget to measure the foot of your bed to get the right size. You measure inside of the frame. Since these are 3 way your inside dimensions have to measure 48 inches for a Super Single, 60 inches for a Queen or 72 inches for a California King.
