Cradlepoint SIM Door Plug for W1855 Wideband Adapter, Weather Sealing

Every W1855 SIM swap happens at height, outdoors, usually in a hurry - and SIM door hardware gets dropped, cross-threaded, or left on the roof. The 170889-000 is the factory replacement: the SIM door plug that closes the W1855's SIM opening and restores the housing's weather sealing. It is a one-piece, quantity-one part, cheap enough to throw into every site kit and critical enough that skipping it turns a five-minute SIM change into a future water-ingress failure. Fleet operators running outdoor 5G adapters keep a strip of these in stock for exactly that reason. SIM bays are the most frequently opened - and most frequently unsealed - compartment on outdoor adapters; a spare door plug in the kit removes the excuse. After seating the SIM, fit the door plug into the W1855's SIM opening and secure it fully per the service guide. Give it the same attention as the cable glands - it is part of the enclosure's sealing system. Cloud Care Networks stocks the Cradlepoint 170889-000 alongside the gateways and routers it supports, so IT and field-service teams can consolidate antennas, spares, and replacement hardware on a single order.
