Milwaukee Battery Door Assembly
Model Number: 31-21-0050
The Milwaukee 31-21-0050 is a genuine OEM Battery Door Assembly for the Milwaukee IR Temp-Gun temperature meters. It is the molded plastic door that covers the three-AA battery compartment on the tool: it latches shut with the battery door lock and opens to load or change the batteries, keeping the batteries enclosed and retained during use. Because it is handled every battery change and latches under spring tension, the door and its latch can crack, wear, or break, and a cracked or missing door leaves the battery compartment exposed and can let the batteries lose contact or fall out. Replacing it with the genuine Milwaukee OEM door restores the correct fit and a secure latch, where an off-spec door may not seat, close, or hold the batteries properly.
This battery door is identified as the Battery Door, Figure 2, on the Milwaukee service parts list for the 2266-20 IR Temp Meter, serial B88A, bulletin 54-07-2240, and it also serves the 2265-20 Temp-Gun and the 2265-20NST and 2266-20NST variants in the same family. The door pivots on the battery door pin, part number 44-60-0235, which is a separate part that Milwaukee has discontinued, so reuse the existing pin from your tool when fitting the new door. Because Milwaukee specifies service parts by serial number as well as catalog number, verify your catalog and serial number against the official Milwaukee service parts diagram before ordering, since running production changes can alter part compatibility within the same catalog number.
