Multiquip M9113400104 Door Stopper

The Multiquip M9113400104 Door Stopper is a genuine OEM component designed for DCA and MQP series super-silent and diesel powered generators, including the DCA300SSC, DCA300SSCU, DCA300SSJU4F, DCA250SSI, DCA250SSIU, and MQP240. Sourced directly from Multiquip, this part matches the original specification and fits into place without any modification to the enclosure. It is compatible across multiple DCA300 and DCA250 variants, making it a reliable choice whether you are servicing a single unit or maintaining a fleet of generators.

Key Features

• Genuine OEM Construction — Manufactured to Multiquip's original design tolerances, ensuring the door stopper holds its position under the vibration and thermal cycling typical of diesel generator enclosures.
• Drop-In Enclosure Fit — Mounts to the existing door panel hardware on DCA and MQP series enclosures with no drilling or bracket modification required.
• Broad DCA and MQP Series Coverage — Confirmed fitment across DCA300SSC, DCA300SSCU, DCA300SSJU4F, DCA250SSI, DCA250SSIU, MQP240, and additional DCA300SSJU4F Tier 4 variants.
• Enclosure Integrity — A functioning door stopper keeps the access panel from swinging freely, preventing hinge stress, panel warping, and damage to wiring or components near the door frame.
• Part Number M9113400104 — Cross-reference this number directly against your unit's parts manual to confirm the correct stopper position before ordering.

The door stopper on a generator enclosure controls how far the access panel opens, holding it in a fixed position so it does not over-extend and stress the hinges or strike adjacent equipment. On super-silent and enclosed diesel generators like the DCA and MQP series, the enclosure panels are part of the sound-attenuation and weather-protection system, so keeping all door hardware in working order is important for maintaining both noise performance and protection of internal components. When a stopper wears out or breaks, the door can swing uncontrolled, risking damage to the panel, hinges, and nearby electrical connections during routine servicing or inspections.
