Dust Cover Latch Spring 54.123

Dust Cover Latch Spring (54.123)

The 54.123 dust cover latch spring provides the tension that keeps the dust-compartment cover latched closed on CleanMax Pro-Series commercial uprights. The spring loads the latch so the cover snaps shut and stays sealed during use, then releases cleanly when you open it to change the bag.

A weak or broken latch spring lets the dust cover pop open or fail to seal, which breaks the airflow path and drops suction. Replacing it with the genuine 54.123 restores proper latch tension. Note that Tacony now supplies the latch and spring together as the B625-0107 assembly; the 54.123 remains available as the standalone spring, and both fit the same CleanMax Pro-Series and Carpet Pro machines.
