The double arm wide panel retainer is used to mount a panel when it is recessed within the T-slot or on the profile frame. The wide arm makes this a stronger connection and also provides stability and reduces vibration. The double arm wide panel retainer is perfect in instances when a profile is connecting two adjacent panels. It requires a drill through machining service on the panel.
