Steven Wehofer of Allegion sent me today’s Fixed-it Friday photo of a magnetic holder modification in a school, and the first thing I thought about was how many kids must be doing pull-ups on it every day. This is not a “fix” that I would recommend.

Probably the only exercise many get for the day.
On a more serious note; I know nothing of magnetic holders other than that they are magnetic. Is there some reason that the door open position is being limited to 90 degrees? A cleaner install would have been to take it back to maximum opening and install with properly sized/angled bracket.. Just asking. FWIW That is one beefy install.
Hi Bruce –
I don’t know why the hardware was specified to only allow a 90-degree opening. Normally the closer would allow the door to swing far enough so the armature mounted on the door would contact the magnet mounted on the wall.

Hard to tell, but it looks like those bolts are no larger than 1/2-20. If those threads are tapped directly into the concrete blocks, each of those screws can only withstand ~170lbf of pull-out force each. And if that force is coming from hanging on the end of a nice 18+” cantilever, it is absolutely possible that a 200 lb teenager bouncing on one of these could pull it off the wall.
Thanks for doing the math! 😀

I hate to admit, but though it’s not ideal, with as well built of a pull-up bar as this is, I much prefer it to some of the door hardware options such as the designed extenders. I would also prefer this solution, especially in a school or other high abuse area to fire closer/holder as I’ve seen more than once how those have broken off (regardless of manufacturer). What would others recommend in lieu of this for a retro fit option?
I would have suggested a 4040se closer instead of this application.
They there need to put some burgers on there or some really nasty tacky sticky stuff that would discourage the kids highly
