KSP 317 Series - 6 or 7-Pin SFIC Tapered Head Mortise Housing

Yes. The KSP 317 Series tapered head mortise housing is built to take either a 6-pin or 7-pin SFIC core, so you can key it into a 6-pin system now and move to 7-pin later without swapping the housing.

It ships with an Adams Rite cam, and that cam is staked on, meaning it is non-interchangeable. You cannot swap it for a standard or other manufacturer's cam in the field, so the 317 is the part to order only when the lock or exit device you are cylinder-ing actually calls for an Adams Rite cam.

The 317 is the housing only. It is the shell and cam that mortises into the device; the small format interchangeable core that actually holds the key bitting is a separate item. For a job where you want the door locked temporarily until the permanent keying is issued, a construction core such as the Corbin Russwin 8000-CT6 BLUE 6-pin interchangeable core is the type of part that drops into an SFIC housing.

Yes, where the existing cylinder is a 1-3/8 inch SFIC mortise housing with an Adams Rite cam. Pull the old housing, retain your existing core if it is a small format interchangeable core, and the keying carries over untouched. If the old housing is a different length or uses a standard or other-brand cam, the 317 is not the match.

They are two different parts and a working mortise cylinder needs both. The KSP 317 is a 1-3/8 inch tapered head mortise housing that accepts a 6 or 7-pin small format interchangeable core; it supplies the threaded body, the tapered head and the cam, but no pins or keys. The Corbin Russwin 8000-CT6 BLUE is the interchangeable core itself, a 6-pin SFIC. If you are building up a mortise cylinder from scratch, order the 317 housing for the door prep and a core such as the 8000-CT6 to drop into it.

The KSP 317 housing accepts small format interchangeable cores in 6 or 7-pin, which is exactly the setup for construction keying. A construction core such as the Corbin Russwin 8000-CT6 BLUE, a 6-pin interchangeable core, goes into the 317 housing during the build; at turnover the control key pulls the core and the permanent core drops in without touching the housing, the cam or the door prep. Keep the 317 housings in place and change only the cores.

It comes down to how the cylinder mounts in the hardware. A mortise housing like the KSP 317 threads into a mortise cylinder pocket and turns a cam to drive the lock, which is why the cam type matters (this one is Adams Rite). A rim cylinder housing sits on the inside face of the door with a tailpiece through a prep, typical of rim exit devices. They are not interchangeable, so check whether your device calls for a mortise cylinder or a rim cylinder before you pick.

That is exactly the case for it. Because the 317 takes standard 6- or 7-pin SFIC cores, you can pin the cores into the same SFIC master key system you use across the rest of the building, while the staked Adams Rite cam keeps it correct for the Adams Rite device. The housing does not determine the keying; the core you drop in does.

If the opening already has an SFIC mortise housing installed and you only need to change who has keys, the core alone is the part to order, and the Corbin Russwin 8000-CT6 BLUE is a 6-pin interchangeable core that pulls with a control key. Order the KSP 317 housing instead when the existing body is damaged, when the cam is wrong for the lock, or when the opening has no SFIC housing yet. The 317 comes with a non-interchangeable staked on Adams Rite cam, so confirm the lock case you are feeding takes an Adams Rite cam before substituting one for the other.

The KSP 317 carries a staked on Adams Rite cam that is not interchangeable, so it cannot be converted to another cam style in the field. Use it where the lock case calls for an Adams Rite cam, typically narrow stile aluminum storefront hardware. For a lock that takes a different cam, select a housing built with that cam rather than trying to adapt the 317. The core itself is not the constraint here, since a 6-pin SFIC such as the Corbin Russwin 8000-CT6 BLUE will seat in any SFIC mortise housing regardless of which cam the housing carries.

Two: Rubbed Dark Bronze and Satin Chrome. Rubbed Dark Bronze reads with dark bronze and oil-rubbed trim; Satin Chrome is the usual match for satin chrome and brushed nickel hardware.

No. The KSP 317 tapered head mortise housing is what shows at the face of the door, and it comes in Rubbed Dark Bronze and Satin Chrome, so match that to the rest of the trim on the opening. The interchangeable core sits inside the housing and is not the visible part, so a core such as the Corbin Russwin 8000-CT6 BLUE is selected on keying and pin count rather than on finish.
