Kawneer KW050451 – Frequently Asked Questions

1) Will the Kawneer KW050451 work on a right-hand door?
No. The KW050451 is built for left-hand applications only. Handing on a mortise exit device is not field-reversible on a service part like this, so a right-hand opening needs the right-hand version instead. Determine handing from the outside of the door: standing outside, if the hinges are on your left, it is a left-hand door.
2) What device sizes does the Kawneer KW050451 exit device part come in?
Two lengths, 36 inch and 48 inch. Pick the one that matches the door width your existing Adams Rite 8400 device was sized for, since the size refers to the device length on the door leaf and not the part number itself.
3) Is the KW050451 compatible with an Adams Rite 8400 mortise exit device already in the door?
Yes. The KW050451 is a genuine Kawneer service part made for the Adams Rite 8400 mortise exit device platform, so it fits the existing 8400 assembly without modification, provided handing (left) and device size (36 or 48 inch) match what is in the door.
4) Is this a complete exit device or just a replacement component?
It is a replacement service component for an installed Adams Rite 8400 mortise exit device, not a new complete device package. If the existing 8400 is beyond repair or you are hanging a new leaf, order a full mortise exit device rather than a service part.
5) I manage a building with several Kawneer aluminum entrances. Can I stock one KW050451 for all of them?
Only for the left-hand openings, and only where the 8400 device length matches the size you stock. Doors handed right need the opposite-hand part, so a facility with both hands on its Kawneer entrances should carry both, in the 36 inch or 48 inch length that matches those leaves.
6) Is a mortise exit device the right choice, or should I look at a rim device?
A mortise exit device like the Adams Rite 8400 pockets into the door edge and latches into the frame jamb, which suits aluminum stile-and-rail entrances where the door is already prepped for a mortise case. A rim device surface-mounts and latches to a rim strike on the stop, so it is the choice when the door has no mortise pocket. Since the KW050451 is a service part for an existing 8400, the decision is already made by what is prepped in your door; swapping device types means new door prep.
7) Is the KW050451 rated for high-traffic commercial openings?
It is a commercial-grade part, built for commercial door hardware use and commonly specified in offices, schools, healthcare facilities, retail, warehouses, government buildings and multi-tenant properties. It is not a residential part.
