DynaLock 2022TJ vs 2022: Inswing or Outswing Maglock Bracket

I've had more than one call where the maglock showed up right and the holding force was right, and it still wouldn't mount. The door swung the wrong way for the bracket in the box. On DynaLock's 2000 Series, that mistake usually comes down to one detail buried in the model number: whether it carries a TJ designation or not. Get that wrong and you're either drilling new holes in a frame that shouldn't need them, or you're boxing the unit back up and waiting on a return.

What the TJ Actually Changes

DynaLock lists the 2000 Series in parallel model numbers that carry identical holding force and identical electrical specs. The only thing that changes between a TJ model and its plain counterpart is which way the door swings relative to the frame the magnet mounts to. Everything else on the spec sheet is the same part, sold two ways.

DynaLock 2022TJ22-US28-HSM2, inswing

DynaLock's own listing calls this out directly as a double electromagnetic lock inswing unit. Order this one when the door swings into the space the magnet armature needs to clear. That's a common layout on stairwell doors and interior pairs, where the corridor side doesn't leave room for a standard mount and the hardware has to sit on the room side instead.

DynaLock 2022-US28-HSM2, outswing

Same holding force, same finish, same monitor option. DynaLock's listing calls this one a double electromagnetic lock outswing unit instead. This is the bracket most exterior doors and most storefront pairs use, since exterior doors typically swing out toward the exit path rather than in toward the lobby.

Both of the units above are double-armature, built for a pair of doors. DynaLock sells the same TJ-vs-standard split on the single-door version of the 2000 Series too, so a one-leaf opening isn't stuck ordering hardware sized for a pair.

DynaLock 2011TJ20-US28-HSM, single inswing

The single-door match to the 2022TJ22 above. Same inswing mounting logic, one armature instead of two, and the same holding force per magnet.

DynaLock 2011-US28-HSM, single outswing

The single-door outswing counterpart, built to the same electrical and finish spec as its TJ sibling. If you're replacing a single failed magnet on a standard-swing door, this is the one that bolts up without a bracket swap.

What Doesn't Change Between Them

Don't let the bracket difference make you second-guess the rest of the spec sheet. It's identical across all four of these units. Every one of them holds 1200 lb, runs on 12 or 24 VAC/VDC field-selectable input, finishes in Satin Aluminum (US28), and shares the same housing footprint at 1-1/2" D x 2-3/4" H x 11" L. Wiring an inswing job and an outswing job on the same project means you're pulling the same voltage and running the same low-power draw either way; the panel side of the job doesn't change, only the bracket.

The narrow 1-1/2" backset is worth noting on its own. DynaLock built these units to skip extra mounting brackets or filler plates on frames where that backset already fits, which is one less part to source and one less thing to get wrong on the order sheet. On a retrofit where the old hardware left a tight opening to work with, that narrow backset is often the reason this line fits where a bulkier magnet won't.

The HSM Option: What You're Actually Wiring

All four of these carry the HSM (High Security Monitor) option, which on the single-door models is spelled out as including a DSM and dynastat force sensor. That's a step up from a bare reed-switch door position monitor. It reports magnet bond status back to the access panel, not just whether the door is shut. If your job spec calls for supervised maglocks rather than a plain, unsupervised setup, this is the pair to order, not the base 2000 Series without the HSM suffix.

If you're still deciding between an unmonitored magnet, a DSM setup, or the full HSM option, that's a separate wiring decision from the bracket question this article covers. See DynaLock DSM2 vs HSM2: Maglock Monitor for a Panel for how those monitor tiers compare on a two-magnet panel and what each one actually reports back.

Picking the Right One for Your Door

Walk the opening before you order, not after the box shows up. Stand at the door and watch which way it travels. If the leaf swings away from you into the room, and the magnet has to mount on the side the door swings toward, that's an inswing condition, and the TJ model is the one you want. If the door swings out past the frame toward you, the standard non-TJ unit is the one that bolts up without modification.

On a pair of doors, check both leaves. It's not unusual for one side of a double door to be the active leaf and the other the inactive standby leaf, and the bracket call can differ between them depending on how the frame is built and which side carries the strike hardware. Measure both before you order two of the same part number out of habit.

Settle the holding force and the monitor tier first, since neither one changes between the TJ and standard versions, then let the door's actual swing direction pick the bracket last. That order keeps you from working backward through a return.

Common questions

Can I mount a non-TJ DynaLock 2000 Series maglock on an inswing door?

No, not without fabricating your own bracket. The TJ and standard versions are built for opposite mounting geometry, and forcing the wrong one onto the frame either leaves the armature misaligned or blocks the door from closing flush. Order the TJ version for an inswing door and the standard version for an outswing door.

Does the TJ designation affect holding force or finish?

No. Both the 2022TJ22-US28-HSM2 and the 2022-US28-HSM2 hold 1200 lb, run the same 12/24 VAC/VDC input, and ship in the same Satin Aluminum finish. The only difference between the two model numbers is the swing direction the bracket is built for.

Do I need the HSM option, or is a plain 2000 Series maglock enough?

That depends on whether your access panel needs to see magnet bond status, not just door-closed status. If the job spec calls for supervised egress hardware, the HSM's built-in DSM and dynastat force sensor gives the panel that reporting. If the door only needs basic door-position monitoring, the plain 2000 Series without HSM is less to wire and less to troubleshoot later in the job.
