This is a listing for a 2 piece padded rail set for a hard sided waterbed. These are the Supreme rail caps and feature a hard frame that doesn’t warp or break. These have 1.5 inch foam and are the drop down cap to give more coverage on the outer sides They are 81 inches long to account for your headboard brackets. If you don’t have waterbed brackets we usually suggest putting them closer to the foot of the bed but you can center them equally also. These are built to order and usually ship FED EX or UPS in about a week. I’m not sure if they have white anymore but I will add it if they do.
