Alarm Controls AM3370 3 Piece Z Bracket Kit for 600 Series Single Magnetic Locks, Clear Anodized (US28)

The Alarm Controls AM3370 is a three-piece Z-bracket mounting kit designed for installing compatible Alarm Controls 600 Series single electromagnetic locks on in-swinging doors. Constructed from clear anodized aluminum with a US28 finish, the adjustable bracket positions the magnetic lock armature for proper alignment with the electromagnet. The AM3370 supports 600 lb magnetic lock applications, including compatible 600S and 600L models, and uses a double-screw mounting design. It provides an alternative mounting configuration for doors where standard outswinging magnetic lock installation is unsuitable.

Alarm Controls AM3370 Three-Piece Z-Bracket Kit for 600 Series Magnetic Locks

The Alarm Controls AM3370 Three-Piece Z-Bracket Kit provides an adjustable mounting solution for compatible 600 Series single-door electromagnetic locks installed on in-swinging doors. Manufactured by Alarm Controls, an ASSA ABLOY Group brand, the bracket assembly enables installers to position a magnetic lock armature on the interior face of a door while maintaining alignment with the electromagnet mounted at the door header. The three-piece Z-bracket configuration accommodates mounting arrangements where conventional magnetic lock hardware cannot be installed directly against the door and frame. Designed for commercial access control installations, the AM3370 supports compatible 600 lb holding-force magnetic locks and features a clear anodized aluminum finish designated US28. The bracket is a mechanical mounting accessory and does not include an electromagnetic lock or electronic access control components.

The AM3370 features a three-piece aluminum construction with an adjustable mounting arrangement that allows installers to position the armature plate relative to the magnetic lock face. The bracket assembly uses a double-screw design for mounting stability and is finished in clear anodized aluminum to provide a consistent appearance with compatible Alarm Controls magnetic lock housings. Published product specifications identify an approximate 10-inch bracket length, 3.5-inch assembled height, and 2 to 2.75-inch adjustment range for the 600 Series Z-bracket mounting arrangement. These measurements describe the mounting configuration rather than the individual dimensions of every bracket component. The AM3370 contains no electrical circuitry, sensors, or power-dependent components. Its performance depends on correct mechanical installation, compatible hardware selection, and proper alignment between the magnetic lock and armature plate.

The Alarm Controls AM3370 is compatible with the 600S and 600L single electromagnetic lock models, as identified in the manufacturer's magnetic lock accessory cross-reference guide. The 600S provides standard single-door electromagnetic locking, while the 600L adds a local status LED. The AM3370 also appears in the manufacturer's compatibility guide for the 600WP weather-resistant magnetic lock, although outdoor installation requirements must be verified separately. During installation, the Z-bracket assembly positions the armature on the pull side of an in-swinging door, allowing the electromagnet and armature to make full contact when the door closes. Proper installation requires sufficient header clearance, suitable door construction, secure mounting hardware, and correct armature alignment. The bracket is intended for single magnetic locks and is not interchangeable with the AM3375, which is designed for 600 Series double magnetic locks, or the AM6370, which supports 1200 Series single magnetic locks.

The AM3370 Z-bracket mounting kit supports electromagnetic lock installations in office buildings, educational facilities, healthcare properties, retail spaces, and commercial interiors equipped with in-swinging doors. Its adjustable aluminum construction allows installers to adapt compatible magnetic lock assemblies to door configurations that require an alternative armature mounting position. The AM3370C provides a related 600 Series Z-bracket configuration with an integrated decorative dress cover, while the standard AM3370 does not include the dress cover. The bracket supports the mechanical installation of compatible 600 lb electromagnetic locks but does not independently provide holding force, fail-safe operation, or electrical control. These functions depend on the installed magnetic lock and associated access control equipment. Installation must follow Alarm Controls mounting instructions and applicable access-controlled egress, fire safety, and building code requirements to maintain proper door operation and locking performance.
