672 Series TouchBar
The 672 Series TouchBar is a high-performance request-to-exit device designed to release electronic locking devices, most commonly electromagnetic locks, when the bar is depressed. Prominent "PUSH TO EXIT" signage provides clear exit indication for building occupants, and the simplified design allows the signage to be reversed in the field. The pivoting bar design activates with just 1/4" of movement, while the slim 2-1/4" low profile offers ample door clearance—significantly less projection than comparable devices in the industry.
The 672 TouchBar is easy to install and simple to wire. Rugged cast ramped end caps deflect impact and provide enhanced durability in high-traffic environments.

Schlage Electronics 672 36 628RD – Frequently Asked Questions
1) Does the Schlage 672 TouchBar lock the door, or is it only a release switch for a maglock?
It is a switch, not a latch. Pressing the bar throws a double pole double throw contact that breaks power to the electrified lock, most commonly an electromagnetic lock, so the door can be pushed open. Nothing on the 672 itself holds the door shut, so all of the security comes from the maglock or electrified lock it controls. Activation happens on 1/4 inch of bar movement, so it releases the moment someone leans into it rather than needing a deliberate push.
2) Will the Schlage 672 TouchBar mount on an aluminum storefront door, and does it ship with the right fasteners?
Aluminum, hollow metal, and wood doors are all covered. The screw pack includes self-drilling and self-tapping screws for the aluminum and wood applications and rivnuts for hollow metal, so on a storefront stile you are not sourcing fasteners separately. Mounting uses a universal system with quick-install brackets, which is why the same bar goes up on all three door materials.
3) I have 36 inch and 42 inch doors in the same building. Do I need a different 672 TouchBar for each opening?
Order to the door: the 672 comes for 36, 42, or 48 inch doors, and every length is available in either finish with red, glow-in-the-dark, or blank lettering. The bar is also field sizeable, so on a mixed set of openings you can stock one longer length and cut it down on site instead of carrying three part numbers.
4) Can I power the Schlage 672 TouchBar from a 12 volt access control panel?
12 or 24 VDC both run it, and maximum current draw is 0.25 amps, so the panel output or the same supply feeding the maglock will carry the device without a dedicated power supply.
5) Can the 672 TouchBar break the maglock power directly and still signal the access control panel?
Both, because the switch is double pole double throw. One pole interrupts the lock power and the second pole is free for shunting the alarm, signaling the panel, or driving an auxiliary relay. Contacts are rated 4 amps at 30 VDC, so size your lock load against that before wiring it inline. Standard cable is 6-conductor 20 AWG, which gives you the conductors for both poles plus the device power in a single pull.
6) I am replacing a worn push-to-exit bar on a maglock door. What do I need to check before ordering a 672?
Three checks. First the door size, 36, 42, or 48 inches, or plan to size the bar in the field. Second the electrical: the device takes 12 or 24 VDC at 0.25 amps, and whatever load you run through the switch has to sit inside the 4 amp at 30 VDC DPDT contact rating. Third the clearance for a 2-1/4 inch projection, which is shallower than a lot of bars coming off. Door material rarely blocks the swap, since mounting is universal and the screw pack covers aluminum, wood, and hollow metal.
7) Will a Schlage 672 exit bar clear a tight vestibule or a door that swings close to a return wall?
Projection is 2-1/4 inches off the door face, a low profile for a touch bar, and that is the number to check against your vestibule or return wall. Bar travel adds nothing meaningful on top of it, since the bar pivots and activates on 1/4 inch of movement rather than stroking deep into the opening.
8) Should I order the Schlage 672 with red or glow-in-the-dark PUSH TO EXIT lettering?
Red is the standard high-contrast marking, ordered as the 672 RD. The glow-in-the-dark version, 672 GID, stays readable when the lights go out, which is worth the upgrade on an egress door where the maglock drops on loss of power and occupants are finding the bar in the dark. A blank bar with no lettering is also available where signage is handled separately. All three lettering choices come in both finishes and in 36, 42, and 48 inch lengths.
9) Does the Schlage 672 TouchBar have to be ordered handed for a left hand reverse door?
Handing is field reversible. The device covers both right hand reverse and left hand reverse applications, and the PUSH TO EXIT signage reverses in the field as well, so one bar out of the carton goes on either swing. On a building with mixed handing that means a single part to stock rather than two.
10) Can the Schlage 672 release an electric strike, or does it only work with electromagnetic locks?
Electromagnetic locks are the common pairing, but the 672 releases other electrified locks as well. What decides it is the switching, not the lock type: a DPDT contact set rated 4 amps at 30 VDC either interrupts or makes the circuit, so any DC lock whose load falls inside that rating can be driven from it, and heavier or AC loads should be switched through a relay instead.
11) I need the exit bar to match dark bronze storefront doors. Does the Schlage 672 come in bronze?
Finish 313 is dark satin bronze anodized aluminum, and 628 satin anodized aluminum is the standard. Both are anodized aluminum meant to sit beside storefront framing, and both are offered across 36, 42, and 48 inch lengths with red, glow, or blank lettering. End caps are powder-coated cast metal.
12) Will a touch bar exit device hold up on a high traffic building entrance?
Construction is heavy-duty aluminum extrusion with powder-coated cast metal end caps, and the end caps are ramped so carts and shoulders deflect off them instead of catching an edge. The bar pivots on 1/4 inch of travel rather than a long mechanical stroke, so there is less movement to wear in over thousands of daily exits.
