Von Duprin 377T US26 – Frequently Asked Questions

1) What does the Von Duprin 377T thumbturn trim actually do on an exit device?
The 377T is the outside trim that pairs with a compatible Von Duprin exit device, and it works as classroom function: the corridor side can be locked or unlocked, while the exit device on the inside always allows free egress. The thumbturn is what controls that locking, so an authorized user changes the state by hand instead of with a key.
2) Do I have to order the 377T thumbturn trim left hand or right hand?
No handing to specify. The 377T is non-handed, so one part covers either swing. That also means you can stock a single trim for a run of classroom doors instead of splitting inventory by hand.
3) Does the 377T come with the exit device, or is it a separate part?
Separate. The 377T is trim only, an accessory that mounts to a compatible Von Duprin exit device. The device itself, and whatever latching hardware the opening needs, are ordered on their own.
4) Will a thumbturn trim still let people out of the room if it gets locked?
Yes. Locking the thumbturn only affects the outside, corridor side. The exit device on the inside stays free at all times, which is what keeps the opening code compliant for egress while the room is secured.
5) Is this thumbturn trim strong enough for a school corridor that sees constant traffic?
It is built to Grade 1, the highest commercial hardware grade, which is the level normally specified for high-traffic institutional openings such as schools, healthcare corridors and government buildings.
6) Can I get the 377T thumbturn trim in a finish that matches my existing black or dark bronze door hardware?
Eleven finishes are offered on the 377T, including 693/SPBLK Black Painted and 622/US19 Flat Black Coated for black openings, and 695/SP313 Dark Bronze Anodized Aluminum, 643E Aged Bronze, 612/US10 Satin Bronze and 613/US10B Dark Oxidized Satin Bronze Oil Rubbed on the bronze side. The remaining options are 619/US15 Satin Nickel, 625/US26 Bright Chrome, 626/US26D Satin Chrome, 605/US3 Bright Brass and 606/US4 Satin Brass.
7) Should I use a thumbturn trim or keyed lever trim for a classroom lockdown?
The difference is who can secure the door and how fast. The 377T thumbturn is operated by hand from inside, so a teacher can lock the corridor side without a key or stepping into the hall. Keyed trim requires a cylinder and a key in someone's hand. Both give classroom function; the thumbturn is chosen where speed and key-free operation matter, keyed trim where you want control restricted to keyholders.
