BEST 12E-72-S2-RP Rim Cylinder Housing - 6 or 7 Pin

About this item

The BEST 12E-72-S2-RP is the Small Format Interchangeable Core (SFIC) rim cylinder housing from BEST Access Systems, sold less core and ready for field installation of a 6-pin or 7-pin BEST SFIC core. It's the housing component specified on rim exit devices, rim panic bars, and rim-mounted lock applications when the door schedule runs on the BEST IC masterkey system.

Decoding the Model Number

Every segment of 12E-72-S2-RP tells you something. The 12E identifies it as part of BEST's 12E Series rim cylinder line, which is machined from solid bar stock. The 72 designates the SFIC housing format, as opposed to standard fixed-core configurations. The S2 specifies the S2 flat spindle, which is the standard steel spindle BEST includes on all 1E rim cylinder assemblies. The RP indicates the ring package is included, which provides the retaining hardware needed to mount the cylinder in the door.

If you're searching for "12e-72 patd," the PATD suffix designates the patent-protected variant of this housing with specific design protections. Confirm the full suffix when ordering if your specification calls for the PATD version versus the standard RP housing.

What "Less Core" Means

The 12E-72-S2-RP ships as a housing only. The SFIC core, either 6-pin or 7-pin, is ordered separately and field-installed using the BEST control key procedure. This is the standard operating model for any IC-based cylinder system. On a new construction project, the housing is installed during rough hardware, and the cores are installed after construction is complete when the permanent masterkey system cores are ready. On a retrofit, existing BEST SFIC cores can be moved into the new housing immediately without rekeying.

The housing accepts both 6-pin and 7-pin BEST SFIC cores, making it compatible with both standard and expanded BEST masterkey system configurations.

What Ships with the 12E-72-S2-RP

The package includes the cylinder housing, the RP ring package, the 1E-S2 standard flat steel spindle, and the clamp plate with clamp plate screws. Everything needed to mount the housing in the door is included. The SFIC core is the only component ordered separately.

Exit Device Compatibility and Interchangeability

BEST rim cylinders are designed to interchange with other manufacturers' rim cylinders. The 12E-72-S2-RP fits the standard rim cylinder hole pattern used on Von Duprin 98/99 rim and vertical rod exit devices ordered less cylinder (LC), BEST 35 Series exit devices, and most other rim-format exit hardware. The cylinder face diameter is 1-5/32" and the cylinder length is 1-11/32". Door thickness range is 1-1/4" to 3".

This interchangeability means the 12E-72-S2-RP can be used on openings where a rim cylinder from another manufacturer was previously installed, without changing the door prep, as long as the clamp plate pattern matches. Non-handed. Installs on right or left hand door without modification.

Masterkey Integration

Any BEST SFIC core installed in the 12E-72-S2-RP can be masterkeyed into an existing BEST IC masterkey system. On a campus or multi-tenant facility already running BEST IC, this housing drops directly into the system without separate system registration. The core carries all the masterkey information, so the housing itself is a neutral component from a keying standpoint.

Available Finishes

The 12E-72-S2-RP is available in standard architectural finishes including 605 Polished Brass, 606 Satin Brass, 613 Dark Oxidized Satin Bronze, 625 Polished Chrome, 626 Satin Chrome, and 632 Stainless Steel. Confirm finish when ordering.
