Cradlepoint 500233-000 SIM Door Assembly Charcoal
Overview
The Cradlepoint 500233-000 is a replacement SIM door assembly in charcoal finish, designed for field maintenance and end-of-life component replacement on Cradlepoint mobile routers and cellular-connected networking equipment. This is the direct OEM replacement part—not a third-party facsimile. The captive screw design prevents fastener loss during installation, reducing the friction of swap-outs in rack environments or field deployments where technicians are managing multiple units across distributed sites.
Compatibility
The 500233-000 is compatible with the Cradlepoint R21X5 series and other Cradlepoint cellular routers that use standard SIM card door mechanisms. Confirm your specific router model supports this SIM door form factor before ordering—SIM doors are model-specific and not interchangeable across all Cradlepoint product lines. If you are unsure which door your router requires, cross-reference your device's model number against Cradlepoint's product documentation or your system integrator's inventory baseline.
Installation Notes
The captive screws are factory-torqued and should be tightened only to the point of seated resistance—do not over-torque, as this can crack the charcoal plastic surround or strip the internal fastener bosses. Installation typically requires only a Phillips-head screwdriver or a multi-bit toolkit. No special tools or pre-staging are needed. Replace the door only when the original shows visible cracks, loose hinges, or damaged latch points that prevent secure seating of a SIM card.
