The Multiquip M3443200803 is a genuine OEM Rear Frame Door designed for DCA125USI3CAN, DCA125USI, and DCA85USJ2 ultra-silent diesel generators. As a direct OEM replacement sourced through Multiquip's authorized parts network, this door is built to the same specifications as the original component on your machine. DHS Equipment supplies this part to keep your generator enclosure structurally sound and performing as intended. Confirm your model code against DCA125USI3CAN, DCA125USI, or DCA85USJ2 before ordering to ensure proper fitment.
Key Features
- Genuine OEM Construction — Manufactured to the same tolerances and material grade as the original enclosure door, ensuring consistent panel alignment and a proper seal against the generator frame.
- Direct Drop-In Replacement — Matches the original mounting points and hinge geometry on the rear frame, allowing straightforward installation without modification to the enclosure.
- Confirmed Generator Fitment — Compatible with DCA125USI3CAN, DCA125USI, and DCA85USJ2 ultra-silent series diesel generators.
- Enclosure Integrity — A properly fitted rear frame door maintains the acoustic and weather-sealing performance of the ultra-silent enclosure, protecting internal components from moisture, debris, and noise bleed.
- Safety-Critical Panel — The rear frame door provides physical access protection over high-voltage generator components; using the correct OEM door ensures latching hardware and panel rigidity meet the original design intent.
The rear frame door is a structural panel on the generator's outer enclosure that closes off the rear section of the machine frame. It protects internal components — including the engine, alternator, and electrical systems — from environmental exposure and unauthorized contact. On ultra-silent series generators like the DCA125USI and DCA85USJ2, the enclosure panels also play a key role in sound attenuation, so a damaged, warped, or missing door can increase operational noise levels and allow moisture or dust ingress. Replacing a worn or damaged rear frame door with Multiquip M3443200803 restores both the protective and acoustic function of the enclosure.
