Dormakaba Rci SA158 5/8 Split Armature Kit Mag Lock

Product Description

The DORMAKABA USA INC. / RCI SA158 is a 5/8 inch split armature kit designed for use with the 8310 series electromagnetic locking system. Split armature assemblies serve as the mounting and contact interface between the mag lock body and the door or frame, allowing the magnetic circuit to complete and hold the door secure when energized. This kit is intended for installation by licensed locksmiths, access control technicians, and security system integrators working on commercial door hardware applications. It is sold as a single unit replacement component.

The SA158 split armature kit is suited for commercial and light institutional access control installations where the 8310 mag lock series is deployed. Split armature configurations are commonly used on doors where a standard Z-bracket or L-bracket mount is not practical, allowing the armature to pivot slightly and maintain consistent surface contact with the lock face. This design is particularly useful on doors with minor alignment variation or hinge play.

Key Features

• 5/8 inch split armature design for improved contact alignment on the 8310 series mag lock
• Replacement kit format — direct swap for worn or damaged armature assemblies
• Sold as a single complete kit (1 EA per unit)
• Engineered for use in commercial access control door hardware systems

Compatibility

Designed as an OEM-style replacement armature kit for the 8310 series electromagnetic lock. Consult the product data sheet and the installed lock assembly to confirm fitment before ordering.

Installation Notes

Installation should be performed by a qualified access control or low-voltage technician familiar with electromagnetic locking hardware. Disconnect power to the mag lock controller or power supply before removing or replacing the armature assembly. Verify door and frame alignment after installation to ensure full armature-to-lock face contact, which is critical for rated holding force. Follow applicable local codes and the manufacturer data sheet for mounting hardware torque and gap requirements.
