- Confirmed MRX-440P Fitment — Verified for use on the Multiquip MRX-440P walk-behind roller; no cross-referencing or adaptation needed.
- Operational Safety Compliance — Restores the machine's reverse alert signal, a required safety feature on construction equipment operating near workers and other machinery.

The back buzzer is an audible reverse-warning device that sounds automatically when the roller is put into reverse, alerting nearby workers to the machine's movement. On a walk-behind roller like the MRX-440P, which operates in close proximity to crews finishing asphalt or compacting base material, a functioning back-up alarm is a critical safety component. When the buzzer fails or stops sounding, the machine may not meet site safety requirements and could pose a hazard — replacing it promptly with the correct OEM part restores both compliance and operator confidence.
