Dormakaba Rci SA138 Split Arm Kit Magnetic Lock

Product Description

The DORMAKABA USA INC. / RCI SA138 is a complete split arm kit designed for use with magnetic lock installations. The kit provides a 3/8 inch split arm assembly that connects the door to the magnet housing, allowing the lock to function correctly when the door is not perfectly aligned with the frame. This type of hardware is installed by locksmiths, access control technicians, and security integrators as part of a complete electromagnetic locking system. The split arm design accommodates minor door and frame misalignment without compromising holding force or lock operation.

This kit is used in commercial and light industrial access control applications where magnetic locks are mounted on doors requiring articulating arm hardware. It is suited for installations using the 8310 series magnetic lock platform. The complete kit includes all components needed for a full split arm assembly, reducing the need to source individual parts separately. Typical installation environments include office entry doors, stairwell doors, and other controlled-access openings.
