Alarm Controls AM3310 - Armature and Mounting Plates for 600 and 1200 Series, For Freezer and Extra Thick Doors

The AM3310 is an armature housing and mounting plate assembly for Alarm Controls 600 Series magnetic locks, made for freezer doors and extra thick doors where a standard flat armature cannot be surface mounted directly. It is the door-side half of the maglock, not the magnet itself, so it goes on a door that already has (or is getting) a 600 Series lock body on the frame.

They differ only by the lock family they mate to. The AM3310 is the freezer and thick door armature housing for 600 Series magnetic locks; the AM6310 is the same style of housing for 1200 Series magnetic locks. Match the housing to the lock body you have on the frame, because the armature and the magnet are a matched pair.

On an extra thick or freezer door, no. The AM3310 (600 Series) and AM6310 (1200 Series) armature housings exist specifically for that condition, where the door slab depth or the insulated construction means a standard flat armature plate will not mount and align to the magnet correctly. Order the housing that matches your lock series rather than trying to shim a standard armature.

Yes. The AM3310 and AM6310 are sold as armature and mounting plate assemblies on their own, so a damaged, missing, or wrong-thickness armature can be replaced without pulling the magnet off the frame. Pick by lock series: AM3310 for a 600 Series lock, AM6310 for a 1200 Series lock.

Clear anodized aluminum, US28. That is the standard maglock finish, so the housing matches the anodized body of the 600 and 1200 Series locks and the usual aluminum storefront framing it gets installed on. There is one finish, so there is no finish choice to make when ordering.

It is a commercial door hardware component, intended for commercial magnetic locking installations such as cold storage, back-of-house freezer doors, and thick exterior slabs. It is not a residential retrofit part.
