Alarm Lock S6197 US26D – Frequently Asked Questions

1) What is the Alarm Lock S6197 and what does it do inside the lock?
The S6197 is a 3-3/4 inch extension link, a genuine Alarm Lock service part that provides the linkage inside compatible Alarm Lock mechanical lock case assemblies. When the link is worn or broken, the lock case loses the connection that drives its operation. Replacing it restores the case to normal function rather than requiring a whole new lock.
2) What length is the Alarm Lock extension link, and does length matter when ordering?
It measures 3-3/4 inches. Length is the whole point of an extension link, so it has to match the lock case it goes into. Alarm Lock builds these to fixed OEM dimensions, so verify the length called for by the lock case you are servicing before you order the S6197.
3) Will the S6197 link fit any Alarm Lock mechanical lock?
No. It fits compatible Alarm Lock lock case assemblies, not every Alarm Lock product. The link is cut to a fixed 3-3/4 inch length, so a case calling for a different link length will not accept it. Identify the lock case model you are repairing and confirm the S6197 is the link that case specifies.
4) Is the S6197 extension link an OEM Alarm Lock part or an aftermarket copy?
It is a genuine Alarm Lock component, supplied through the brand's own parts and accessories program as a replacement part. For maintenance teams that have to keep a documented OEM repair on commercial openings, that matters more than the price of a generic link.
5) What finish does the S6197 extension link come in?
One finish only: 26D, satin chromium plated over nickel. Since the link sits inside the lock case and is not visible once the lock is assembled, the finish is about corrosion resistance and smooth internal movement rather than matching trim on the door.
6) Is this extension link suitable for commercial buildings or is it a residential part?
Commercial. Alarm Lock classifies the S6197 for commercial mechanical lock applications, and it shows up in office buildings, schools, healthcare facilities, retail, warehouses, multi-tenant residential, and government buildings where Alarm Lock hardware is installed.
7) Should a locksmith stock the S6197 extension link for service calls?
If you maintain Alarm Lock mechanical locks across a portfolio, yes. It is a wear component in the lock case, and carrying the link means a broken linkage is a bench repair on site instead of a return trip with a complete lock case. That is the reason Alarm Lock sells it as a discrete replacement part.
