Falcon STK170 – Frequently Asked Questions

1) What is the Falcon STK170 and what does it do on a pair of doors?
The STK170 is a pair of adjustable mortise strikes used with Falcon aluminum removable mullion assemblies. They mount in the mullion so the latchbolts of the exit devices on each leaf of a paired opening engage properly. Because they adjust, you can fine tune alignment to the latch in the field instead of shimming or re-drilling the mullion.
2) Which Falcon mullion and device sizes do the STK170 strikes cover?
The STK170 is ordered against the mullion and device size combination: RM170 mullion with a 1790 device size, or RM70 mullion with a 2090 device size. Match the mullion model stamped on your existing removable mullion and the device size before you order, because the strike is cut for that pairing.
3) My doors are rubbing or the latch is not catching on the mullion. Do I need a whole new mullion?
Not necessarily. If the mullion itself is straight and undamaged, worn or misaligned strikes are the usual cause, and the STK170 adjustable mortise strikes let you reset latch engagement without replacing the mullion or the exit devices. That is the point of a replacement part like this: service the failing piece, leave the rest of the assembly alone.
4) Will the Falcon STK170 work on a single door or a pair without a mullion?
No. These are mullion strikes. A single door or a pair with no center mullion latches into the frame or into surface or concealed vertical rods at the head and sill, so the STK170 has nothing to mount into. Use it only where a Falcon removable aluminum mullion is installed between the leaves.
5) Does the Falcon STK170 come as one strike or two?
Two. The STK170 ships as a pair, which is what a center mullion opening needs since each leaf latches into its own strike. Ordering one part number covers both sides of the mullion.
6) Is the STK170 strike rated for commercial traffic, or is it a residential part?
Commercial. Falcon lists the STK170 as a commercial exit device part, and it is the strike used on high traffic egress openings in schools, hospitals, offices, retail and government buildings where paired doors run on a removable mullion.
7) Is the STK170 a genuine Falcon part or an aftermarket strike?
Genuine Falcon. It is cataloged as a Falcon exit device replacement part, so the mortise cut and mounting match the original mullion prep rather than needing to be filed to fit.
