KSP 702S Screw On Mortise Housing Cam

The 702S is the cam that mounts on the back of a mortise cylinder housing and transfers key rotation to the lock case. It is a screw-on cam cut to the Sargent pattern, so it drives Sargent mortise lock hardware. Without the right cam on the back of the housing, the cylinder turns but the lock does not actuate.

No. The 702S is cut to the Sargent cam pattern, so it is the part to use when the mortise lock body is Sargent. Cam shape is manufacturer specific, so a lock from another maker needs the cam matched to that maker's pattern instead.

Just the cam. The 702S is a component of a mortise cylinder assembly, not a cylinder and not a core. If you need the actual keyed core, that is a separate item, for example an interchangeable core such as the Corbin Russwin 8000-CT6 blue construction core.

No. The KSP 702S is a screw-on mortise housing cam sized for Sargent, the small tailpiece-style part that mounts to the back of a mortise cylinder housing and actually throws the lock mechanism. The Corbin Russwin 8000-CT6 BLUE is a 6-pin interchangeable core, blue construction core - the keyed plug that drops into a housing. One is the driven part, the other is the keying part, so they are not alternatives to each other. If your cylinder turns but the lock does not operate, the cam is what you are after; if the key is the problem, you are looking for a core.

Screw-on. The 702S fastens to the mortise housing with screws rather than snapping on, which is the more common arrangement on interchangeable core mortise housings and lets the cam be swapped without replacing the housing.

That is exactly the use case. KSP mortise housings take a screw-on cam, so a maintenance shop can stock housings and cores and fit the 702S Sargent cam on the openings that have Sargent lock bodies, rather than buying a different complete cylinder for each lock brand in the building.

The 702S is not a construction-keying item. It is a screw-on mortise housing cam for Sargent housings and stays in place permanently regardless of how the opening is keyed. For temporary keying during construction, the part that does that work is a construction core such as the Corbin Russwin 8000-CT6 BLUE, a 6-pin interchangeable core supplied as a blue construction core that is pulled and swapped for the permanent core at turnover. On a Sargent mortise housing you may well need both: the cam to drive the lock and a core to key it.

One. It is sold as a single model, 702-S, with no finish or size choices to specify. You pick it based on the lock it drives, which is Sargent.

The 702S is classed as interchangeable core hardware - it is the screw-on mortise housing cam used with Sargent mortise housings that accept an interchangeable core, rather than a cam for a conventional one-piece mortise cylinder. That puts it in the same hardware family as an interchangeable core like the Corbin Russwin 8000-CT6 BLUE, though the two do different jobs: the 702S drives the lock, the core carries the keying.
