Kawneer KW450350 – Frequently Asked Questions

1) What is the Kawneer KW450350 threshold screw spline used for?
The KW450350 is a threshold screw spline, a genuine Kawneer service replacement part for 36 inch exit device installations. It sits in the threshold and gives the screws something to bite into, holding the threshold and the exit device assembly in proper engagement. It is a commercial-duty replacement part, not a complete exit device or threshold.
2) Will the Kawneer KW450350 spline work on a left-hand door?
No. The KW450350 is designated right-hand only. Threshold splines on offset pivot doors are cut to the pivot side, so a left-hand opening needs the left-hand part number instead. Stand outside the door: if it swings away from you on hinges or pivots to your right, it is right-hand and this is the correct part.
3) Does this Kawneer threshold spline fit a 42 inch door?
No. The KW450350 is built for 36 inch exit device configurations. Wider or narrower openings use a different spline length, so match the part to the device width before ordering.
4) Is the KW450350 for a closed back or open back frame?
Open back frames. The KW450350 spline is cut for open back frame assemblies with an offset pivot, single acting, single door setup. If your frame is closed back or the door is center hung or double acting, this is not the matching spline.
5) Can I use the KW450350 on a pair of doors?
It is specified for a single door. The KW450350 covers a single acting, single door opening on an offset pivot. A pair of doors needs the spline configured for that opening, and each leaf is handed separately.
6) Do I have to replace the whole threshold if the spline is stripped?
Not necessarily. The KW450350 is sold as a drop-in service part for compatible Kawneer exit device assemblies, so a stripped or damaged spline can be swapped without pulling the entire threshold and device. That is the point of stocking it as a service component for maintenance on existing Kawneer openings.
7) What information do I need before ordering a Kawneer threshold screw spline?
Four things decide the part number: device width (this one is 36 inch), pivot type (offset pivot), door action and count (single acting, single door), frame type (open back), and handing (right hand). Get any of those wrong and the spline will not line up with the threshold screw pattern. Pull the old spline or check the original Kawneer door schedule before you order.
8) Is the KW450350 spline an OEM Kawneer part or an aftermarket copy?
It is a genuine Kawneer service part, made to Kawneer specification. For a facilities or MRO buyer standardizing on Kawneer storefront and entrance hardware, that matters: the spline has to index correctly with the existing threshold and device prep, and an approximate substitute will not hold the screw pattern.
