The Multiquip M3443200503 Rear Frame Door is a genuine OEM component designed for DCA125USJ, DCA150USJ, DCA-70USJ, and DCA85USJ ultra-silent generator models. As a factory-sourced part, it is manufactured to the exact tolerances and dimensions of the original, ensuring a correct, secure fit within the generator enclosure. This replacement door is the right choice when the existing panel is damaged, warped, or no longer sealing properly, and it confirms compatibility with the DCA ultra-silent series across all four listed models.
Key Features
- Genuine OEM Construction — Manufactured to the original panel dimensions and material specification, so fitment and enclosure integrity match what left the factory.
- Direct Panel Replacement — Mounts to the existing rear frame aperture on DCA-series enclosures with no modification to mounting points or hardware positions.
- Confirmed DCA Series Compatibility — Verified fit for DCA125USJ, DCA150USJ, DCA-70USJ, and DCA85USJ ultra-silent generator units.
- Enclosure Seal Integrity — A correctly fitted rear frame door maintains the acoustic and environmental seal of the generator housing, preserving noise-reduction performance and protecting internal components from dust and moisture ingress.
- Structural Access Panel — Provides proper rear-access closure to the frame, supporting safe servicing of internal components while keeping the enclosure structurally intact during operation.
The rear frame door is a structural panel that forms part of the generator's outer enclosure. On ultra-silent generator models, this enclosure is engineered to dampen operational noise and shield internal engine and alternator components from the elements. When the rear door is cracked, misaligned, or missing, the acoustic lining is compromised and internal components are exposed to airborne debris and moisture — both of which can accelerate wear on sensitive electrical and mechanical parts. Replacing it with the correct OEM panel restores the enclosure to its intended condition.
