The set of rails is a presentation that includes both the lower rail and the upper rail of the Space + system. The set of these rails is designed to guide the sliding doors and can support a weight of up to 85 kg. Both pieces are manufactured with aluminum and have a natural aluminum finish. These rails are compatible with the installation of slowmove brakes and soft closures and both have a length of 2.35 m. Each package contains a total of 2 units that, due to their weight, are easily manageable and only need screws or plastic clips for installation.
