The Multiquip M1443200803 is a genuine OEM Rear Door designed for DCA-series ultra-silent diesel generators, including the DCA45SSIU3, DCA45SSIU2, DCA45SSIU2-GEER, DCA45SSIU3-60HZ, DCA45SSIU3-50HZ, DCA45SSIU2-FEMA, and DCA36SPX. Sourced directly from Multiquip, this replacement door is manufactured to the same standards as the original enclosure component installed at the factory. It is a direct-fit replacement that restores the structural and acoustic integrity of the generator enclosure. Confirm your model code before ordering to ensure correct fitment across this generator family.
Key Features
- Genuine OEM Construction — Manufactured by Multiquip to the exact panel dimensions and latch interface of the original enclosure, ensuring a proper fit without reworking hinges or mounting points.
- Enclosure Acoustic Performance — Restores the sound-attenuating enclosure seal that DCA ultra-silent generators depend on to meet low-noise operation ratings on sensitive jobsites.
- Broad DCA-Series Compatibility — Confirmed fitment across DCA45SSIU3, DCA45SSIU2, DCA36SPX, and associated variants including 50Hz, 60Hz, FEMA, and GEER-configured units.
- Structural Integrity Restored — A damaged or missing rear door exposes internal generator components to weather, dust, and debris; replacing it protects the alternator, engine, and control systems from environmental damage.
- Direct OEM Replacement — Part number M1443200803 matches the original Multiquip bill of materials, eliminating guesswork when sourcing through dealers or service centers.
The rear door is a structural panel of the generator's sound-attenuating enclosure, forming one of the sealed outer walls that surrounds the engine and alternator assembly. On ultra-silent series generators like the DCA45SSIU3 and DCA45SSIU2, the enclosure as a whole is engineered to significantly reduce operational noise levels, and the rear door plays a direct role in maintaining that acoustic barrier. When the door is damaged, bent, or missing entirely, the enclosure can no longer seal correctly — allowing noise levels to rise, weather protection to fail, and internal components to be exposed to contaminants that accelerate wear.
