This product is a 304 solid Stainless Steel rail connector. The decorative hardware is used to connect or attach two rails together. The product will maintain a flush surface so there won’t be a disruption in the smoothness of the roller as it continues to roll from one side to another on the rail. The stainless steel hardware is held in place by a series of six rubber washers (three on either end). These keep enough friction between the rail and connector so the two don’t come apart.
