Kaba Ilco 7075SC10-26D Rim Cylinder

The Kaba Ilco 7075SC10-26D is a 5-pin rim cylinder in the Schlage C keyway, finished in 26D satin chrome. The cylinder is drilled for 6 pins and pinned in 5, which is the standard commercial configuration that allows upgrading to a 6-pin keying specification without replacing the housing. Rim cylinders are the standard outside cylinder format for rim-mounted exit devices, surface-applied deadlocks, and other hardware where the cylinder mounts to the door face rather than inserting into a mortise or bored-hole preparation. A keyed alike option is available at ordering.

What rim cylinders are used for and how they differ from mortise cylinders

A rim cylinder is a distinct cylinder format from a mortise or cylindrical cylinder. Where a mortise cylinder inserts into a lock body through a threaded hole and a cylindrical cylinder installs inside a bored-hole lock chassis, a rim cylinder mounts externally to the door face with a cam or tailpiece on the back that actuates a rim-mounted mechanism. The cylinder body is visible on the outside of the door; the cam on the back engages the locking mechanism directly.

The most common application for rim cylinders is outside trim on rim exit devices, where the cylinder provides keyed outside entry while the inside push bar provides free egress. Rim deadbolts, surface-applied door locks on metal doors, and some storefront applications also use rim cylinders. The format is also used on certain chain door guards and auxiliary locks where a surface-mounted cylinder is the only practical installation option. Because the cylinder mounts externally rather than through the door prep, it's accessible for replacement or rekeying without disassembling the lock body.

Schlage C keyway compatibility and the 5-pin drilled-for-6 configuration

The Schlage C keyway is one of the most widely distributed commercial keyways in the US market. Cylinders in the Schlage C keyway accept the same key blank profile used across Schlage's conventional cylindrical lock line, which means the 7075SC10-26D can be keyed into an existing Schlage C keyway master key system without specifying a proprietary keyway. This makes it a practical replacement cylinder on buildings already running Schlage-keyed hardware.

The 5-pin, drilled-for-6 configuration means the cylinder has 6 pin chambers machined into it but only 5 are loaded with pins in the standard configuration. A locksmith can upgrade to 6-pin pinning for higher key-change combinations without replacing the cylinder housing. Five-pin is the standard commercial specification for most applications. Six-pin is specified when the master key system requires a greater number of change key combinations than 5-pin chambers support. The keyed alike option at ordering allows multiple cylinders to operate on the same key, which is useful when the same key should open both the outside rim cylinder and other locks in the building.

Finish, installation, and related cylinder options

The 26D satin chrome finish is the most commonly specified commercial finish for exit device trim and surface-mounted hardware. It coordinates with satin stainless steel exit devices, satin chrome lever hardware, and the majority of commercial aluminum door frames. The rim cylinder installs using the standard rim cylinder mounting method: the cylinder body passes through a prepared hole in the outside trim, and a mounting ring or backing plate on the interior face secures it to the door or device chassis.

The broader rim cylinders section covers compatible options from other manufacturers for the same exit device and rim hardware applications. For exit devices and exit hardware that commonly pair with rim cylinders, the exit hardware section covers coordinating panic devices, trims, and strikes.

Confirm the keyway matches your existing master key system and verify the pin count requirement before ordering. The keyed alike option must be specified at time of order.
