In order to allow a sliding door system to come further forward, because you are dealing with a frame for example, these round supports offer the solution. This set of 5 round supports have a length of 50 mm instead of the standard 35 mm. This ensures that the rails of the sliding door system come further forward, so that the sliding door can easily slide in front of the doorway. The round supports have a matt black coating and are supplied with fasteners.
