Trine MWH-5 - Removable Mullion Wire Harness for 4800 Series Electric Strikes

The MWH-5 kit ships with a 5 foot mullion wire with male and female connectors, one male connector, one female connector, four wire caps, one wire tie, one mullion cap, and wire adhesive. It's a replacement part kit, so everything in it is the wiring hardware for the mullion run itself, not the strike.

That's exactly what it's built for. The MWH-5 is the removable mullion wire harness for Trine 4800 Series electric strikes, and the male/female connector pair is what lets the mullion be pulled out without cutting or re-splicing the strike wiring. It is not a harness for other Trine strike families.

No - they are two different kinds of part. The Trine MWH-5 is a removable mullion wire harness kit: a 5 foot mullion wire with male and female connectors, plus a male connector, a female connector, four wire caps, a wire tie, a mullion cap, and wire adhesive. It carries power across a removable mullion to a 4800 Series electric strike; it is not a locking device itself. The Adams Rite 7400A is an Ultraline electric strike body kit with field selectable fail safe / fail secure operation - that is the strike body that does the latching work in the frame. A 7400A does not replace the harness that feeds a removable mullion, and the MWH-5 does not replace a strike body.

The harness wire is 5 feet, which covers the run from a strike mounted in the mullion to the connector point on a standard opening. If your run needs more than that, you're wiring past the harness and the extra length has to come from your own field wiring above the connector.

No. The Adams Rite 7400A Series Ultraline body kit is not fire rated, so if the mullion opening you're wiring is a fire door assembly, that kit is the wrong direction and you should be specifying a fire rated strike instead. The MWH-5 harness itself is wiring hardware, not the rated component.

Not on a fire rating basis. The Adams Rite 7400A Ultraline electric strike body kit is listed with a fire rating of No, so it is not the part to specify when the opening requires a fire rated strike. Note also that the fire question belongs to the strike body, not to the wiring: the Trine MWH-5 is the removable mullion wire harness that carries the connection to a 4800 Series electric strike, supplied with a 5 foot mullion wire, male and female connectors, wire caps, a wire tie, a mullion cap, and wire adhesive. Confirm the strike model against the fire requirement first, then wire it.

Commercial. The MWH-5 is a commercial electronic access control part, which is the environment removable mullions live in anyway: storefront and exit device pairs, not residential doors.

One model only, MWH-5. There are no length, finish, or connector options to specify, so the order is just the part number.

No. The Trine MWH-5 belongs to the Trine MWH-5 series and is a removable mullion wire harness for Trine 4800 Series electric strikes. The Adams Rite 7400A is part of the 7400 Series, a separate Adams Rite line of Ultraline electric strike body kits. Ordering by series matters here: MWH-5 identifies the mullion harness kit, while 7400 Series identifies an Adams Rite strike body.
