Shelley 2inch Mast Coupler Sturdy 2″ Aerial Mast Joiner Coupler A device which enables two 2″ diameter masts poles to be coupled ‘joined’ to achieve a greater height i.e. 2 x 12′ masts = 1 x 24’mast. We use these couplers a lot with patio ground mounts and NPRM (Non penetrating Roof Mounts) when satellite dish and aerials require mounting and extra height on the pole is required.
