KSP 407 Series - 6 or 7-Pin SFIC Mortise Housing With Cam Pack

The KSP 407 is the mortise housing that accepts an interchangeable core, not the core itself and not a complete lock. You mortise the housing into the door or cabinet, screw the removable cam on the back, and drop your keyed core into the figure-eight opening. The core is ordered separately. It takes a 6 or 7-pin small format core, and the cam pack ships with the housing so you have the tailpiece to drive whatever you are latching.

Both, depending on which one you order. The 407 comes in an SFIC housing for small format figure-eight cores, an LFIC housing for large format cores, and an SFIC - Long version. Small and large format cores are not interchangeable with each other, so match the housing to the core family your building is already keyed on before you order.

Either one. The 407 SFIC housing is built for 6 or 7-pin small format cores, so a facility standardized on 7-pin (common where a master key system needs the extra pinning depth) drops straight in, and so does a 6-pin core. The core body is the same figure-eight profile in both pin counts.

No, the cam pack comes with the housing. The cam is the screw-on type and is removable, so if the first cam does not match the lock or cabinet mechanism you are driving, you back the screw out and fit a different one from the pack rather than replacing the whole housing. What you still need to supply is the keyed core.

No - they are two halves of the same assembly, not alternates. The KSP 407 is a 1-3/8 inch mortise housing with a screw-on removable cam and a cam pack, sized to accept a 6 or 7-pin SFIC core; it is the shell that mounts in the door or cabinet and drives the lock through its cam. The Corbin Russwin 8000-CT6 BLUE is the core itself, a 6-pin interchangeable core supplied as a blue construction core. Ordering the 8000-CT6 BLUE when a housing is what came out of the door leaves you with a cylinder and nothing to seat it in, and ordering the 407 alone leaves you with a housing and cam but no keyed plug.

Length behind the door face. The standard SFIC housing is the 1-3/8 inch body, and the SFIC - Long is the extended version for applications where the cam has to reach further back, typically a thicker door or a deeper cabinet face. Measure from the face of your prep to where the cam needs to engage, then pick accordingly. Both accept the same 6 or 7-pin small format core.

The 407 is sold as the housing and cam only, so you pair it with a separate interchangeable core in the matching format. If the space is still under construction, a construction core is the normal move: the Corbin Russwin 8000-CT6 is a 6-pin interchangeable core supplied as a blue construction core, which lets the trades work on a temporary key and then gets swapped for the permanent core at turnover without pulling any hardware. Make sure whatever core you pick is the same format as the housing you ordered.

That is the point of it. With an interchangeable core housing, a control key pulls the core out of the face and a new core goes in, so rekeying a unit after a tenant turnover or a lost key takes seconds at the door and no disassembly of the housing or the lock. The housing and its screw-on cam stay mortised in place. For a property manager running a large fleet of doors, that is the difference between a locksmith call and a maintenance tech with a box of cores.

A KSP 407 ships as the housing, the screw-on removable cam and a cam pack, and it takes a 6 or 7-pin SFIC core to become a functioning cylinder. The core is a separate line item, and it is what carries the keying - which is why an interchangeable core job is usually written as two part numbers. Corbin Russwin's 8000-CT6 BLUE is an example of the core side of that pairing, a 6-pin interchangeable core furnished as a blue construction core for jobsite keying before the permanent cores go in. Confirm the core format and pin count you are keying to before pairing, since the 407 is offered in SFIC, SFIC - Long and LFIC housings.

Two: Oil Rubbed Bronze and Satin Chrome. Satin Chrome is the one that reads closest to the 626 satin chrome finish on most commercial lever and cylinder hardware, so it is the usual pick when you are matching existing openings in an office or institutional building. Oil Rubbed Bronze suits dark bronze storefront and residential-grade trim. Both finishes are offered across the SFIC, LFIC and SFIC - Long housings.
