How Not To Install A Mag Lock

One of my techs sent me this pic from an install we are working on.

That air gap between the magnet and frame is just begging for trouble.  Instead of using the bond force of the maglock to keep the door closed, it could be used as leverage for pulling those bolts out or breaking them off clean.

The cable 'protection' is a mess too.  Someone could cut those wires from the outside provided they could get a blade on top of the lock from the outside. (Not to mention cutting the bolts holding it on.)  A maglock without power is not a lock at all!

In retrospect, using a Z or a two L brackets to relocate the point where the armature meets the magnet seems to make better sense.

What are you going to do to fix it?  Are they letting you fix it?

Looks to me like that was Rev 2 of that lock install. You can see mounting holes and lock/spacer outline in the header from the previous install.  We usually use spacing blocks from the manufacturer.  That said, I'm not sure how much weaker it is from the outside. Those mounting bolts are thicker than a lot of screws that come with the lock kits, and I'm not sure they would be accessible from the outside.  

I'm more curious how those threaded rods are affixed to the top mounting plate.  They're usually pre drilled and have to flush fit the Mag lock.  

(Edit) after re-looking at it, it appears that that type of lock is not using the top bracket plate.  Looks like those bolts are going straight through from the bottom of the lock.

I doubt that door header is threaded, so my guess it they are blind sunk into the masonry block and grout above.  There might be a set of nuts up there, but it is hard to see if there is a gap in that picture.

We are installing CCTV and not doing anything with access control yet.  Though this gives me ammunition to take it over.

You can go in there and point out a few problems like this and *boom* before you know it, talk yourself into a project fixing it.  No good deed goes unpunished!

Oh I know but this is part of a 130 location project which we are installing cameras for the next 2 years.   I would love to take over the access control and we will at some point but right now I would need 10 more guys to handle it.

Easy answer, DO NOT USE MAGLOCKS, get a qualified locking hardware specialist to find the right solution for the door, best solution always is for "latching hardware" that is Fail Secure when there are power interruptions.  Maglocks should only be used a last resort when all other options are exhausted.

I would bet there is a REX that does RTE Unlock on activation which is a HUGE risk on a perimeter door, another example of what Maglocks are a bad choice.

I recommend that you do not use Security VAR's to do locking hardware work unless they have qualified door hardware/locking specialist on project staff so you don't have these kinds of issues.

Locking hardware and installation is a sub-culture (no disrespect intended whatsoever). Definitely leave to people who know what they're doing! If the installer can't recite 179 model numbers of choices and the pros and cons of each, don't trust them to do an excellent job. (Yes, 179 is a random number!)

And yet, I've seen worse.

I suppose if that frame is filled with cement then getting those wires through the frame would be a challenge, could be done though. I don't think I have ever seen a maglock with two cables coming out of it, even it there is a built in door contact or bond status.

Is that a wad of chewing gum being used to hold up the wires on the right side?

Steel frame, probably ANSI prep for the lockset hardware = absolute no-brainer for a strike application.

To bad they didn't use the CWB mounting bracket for it. Securitron has a bracket for their mag locks just for those circumstances. Not sure how you can walk away from that and say "Yep I installed that" knowing it is horrible.

Looks like the lock has perfect cooling :-)
