The Lantronix BR351 DIN Rail Clip is the manufacturer's mounting accessory for G520 Series cellular gateways. It lets you mount the gateway on DIN rail, which is the standard in industrial control cabinets, electrical panels and equipment enclosures. The clip is metal and has a single-mount, 7½ U width design. Each BR351 comes with one metal DIN clip, two gaskets and two M3x6 screws, which is all the hardware needed to fit the clip to the gateway. For integrators and field teams, the BR351 is a simple way to keep G520 Series installations consistent across sites. It is useful when a gateway is moving from a desk or shelf into a cabinet, when you are replacing a lost or damaged clip, or when you are stocking spare mounting hardware for a rollout. Lantronix also includes the BR351 in its G526 and G528 accessory bundles, so ordering it separately gives you the same mount those kits use.
