The single retainer profile can be cut to your desired length. There are options available in mill or black anodize finish. It is commonly used to mount a panel or mesh when it is recessed within the T-slot or on the profile frame. When used in this capacity it is a strong fastening option that is simple to use, provides stability, and reduces vibration. The single retainer profile is also frequently used when mounting one panel or mesh to a T-slot profile or in instances when larger profile series are used to mount two panels or mesh.
