The maglock is designed to be mounted so the armature is face to face with the maglock. In your mount, you have it in a shear/sliding situation. You won't have anywhere close to 1200#s of holding force if you can get it to bond at all. The armature has to float which allows for a small degree of misalignment. The maglock's capability to "****" the armature in is very limited. Before you get too deep, I would get the door back on and swinging and sort out the lock mounting. If you don't have the armature, I would scrap the maglock. The armature has to be extremely flat ( think surface ground) to effectively bond. Feel free to PM me or post here with any questions
