At PartsPuppy.com we have replacement end cap inserts for outdoor patio furniture. End caps and inserts typically fit inside the sling rail or other tubular opening in the chair or chaise. These inserts or caps keep water and debris out of the tubes. It is important to keep these caps in place because freezing water, that has collected in the frame or sling tube can cause the tube to swell and break. This effectively ruins your outdoor furniture. Replace those missing end cap inserts. Just look through or wide selection of end cap inserts to find the ones that are right for your outdoor chairs and chaise lounge patio and pool furniture.
