Von Duprin VON-379L-BE-626 – Frequently Asked Questions
1) Will the Von Duprin 379L-BE trim work on any rim exit device, or only certain Von Duprin models?
The 379L-BE escutcheon trim is built for Von Duprin 55 Series rim exit devices. It is not a universal trim, so if the device on the door is another series or another brand, you need the trim made for that device. Match the device series before ordering.
2) Does the 379L-BE blank escutcheon take a cylinder for outside key access?
No cylinder. The 379L-BE is a blank escutcheon with an always-operable function, meaning the outside lever always retracts the latch and there is no key control from the outside. Use it where you want free passage in from the outside, or exit-only with a pull. If you need to lock the outside lever and key it, you need a keyed control trim instead of the blank.
3) Do I have to specify handing when I order a 379L-BE escutcheon trim?
Yes, handing is required. The 379L-BE is ordered as either RHR (right hand reverse) or LHR (left hand reverse). Exit doors swing out, so the hand on a panic device is almost always a reverse hand: stand outside the door, and if the hinges are on your right it is RHR.
4) Can I use the 379L-BE on a fire-rated door assembly?
Yes. The 379L-BE supports ANSI/UL 10C and CAN/ULC-S104 fire-rated configurations, and is also certified to ANSI/UL 305 and CAN/ULC-S132 for panic hardware. Because the trim is always operable with no cylinder, there is no mechanical dogging concern through the trim on a fire door.
5) I want a plain plate with no lever at all on the outside. Is the 379L-BE the right part?
No. The 379L-BE is a blank escutcheon that carries a lever, so the outside lever always operates the latch. If you want a true blank plate with no operating trim, the Sargent 802 blank plate exit device trim is that type of part. For a pull rather than a lever, the Sargent 814 PSB nightlatch pull or the 862 offset pull handle cover that need.
6) I need the outside lever to lock, not be always operable. What trim should I look at instead?
The 379L-BE is always operable with no cylinder, so it cannot be locked from the outside. For a keyed classroom function, the Corbin Russwin K157ET key-only trim (ED2200/ED2400 devices) or the Detex 08BN classroom S-lever with mortise cylinder are Grade 1 alternatives. For a storeroom function lever, Deltana offers the DDS-36 for 80-series devices and the LTED60LST for 60-series. Each one is tied to its own device series, so match the device first.
7) What looks like a substitute for the 379L-BE but will not work on a 55 Series rim device?
Several trims share the blank or pull concept but are cut for other chassis. The Sargent 802 blank plate is a PE80 Series trim and is not rated for wood doors. The Sargent 814 PSB is a heavy duty night latch pull for 80 Series devices, and the Sargent 862 is a Grade 1 offset pull handle in the P800 Series. The Detex A/AN Series blank escutcheon pull trim is for Detex Value Series devices, and the Detex 90 Series keyed removable mullion is not a trim at all but a mullion for rim exit devices. The Von Duprin 379L-BE is engineered specifically for Von Duprin 55 Series rim exit devices.
8) I need a lever trim with a locking function rather than always operable - what are the options?
The Von Duprin 379L-BE is an always operable trim with no cylinder, so the outside lever never locks. For a locking function, the Deltana LTED60LST is a storeroom function lever trim for 60 series exit devices and the Deltana DDS-36 is a storeroom lever trim for 80 series devices; the Deltana LTED80LS is entry function and the LTED80LP is passage function for 80 series. For classroom function, the Arrow SRX87 Sierra lever with rose fits S1150/S1250/ED910/PEC910 Series devices on 1-3/4 inch doors.
9) Which lever design do I pick with the 379L-BE, and does it have to match my other doors?
Seven lever designs are offered with the 379L-BE: 01, 02, 03, 06, 07, 12 and 16. A lever choice is required at the time of order. If you are adding doors to a building already running Von Duprin trim, specify the same lever number and the same finish code so the new openings match the existing ones.
10) What finishes does the Von Duprin 379L-BE escutcheon come in for matching existing hardware?
Eight finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze, 625 bright chrome, 626 satin chrome, 643E aged bronze, and 693/SPBLK black painted. For a commercial corridor already in 626, satin chrome is the usual match; 613 and 643E are the darker bronze options for hospitality and retail fronts.
11) Is the 379L-BE heavy duty enough for a school or hospital corridor door?
It is certified to ANSI/BHMA A156.3 2014 Grade 1 and rated heavy duty for commercial use, which is the top grade for exit hardware and the level facilities standardize on for high-traffic corridors in schools, healthcare and government buildings.
12) Is there an electronic access control trim option if I later want credentials on the door instead of a lever?
The 379L-BE itself is mechanical with no cylinder, but it sits in Von Duprin's modular 370 Series control trim platform, which is built so options can be added as mechanical and electronic technology converge. If you want keypad control now, the BEST EXZ EZ Series electronic keypad exit trim with key override and the Dormakaba E-Plex E5010 push button trim (Grade 1, 1-3/8 to 2-1/4 inch doors) are the electronic trims in that class.
13) I have a pair of doors with 55 Series rim devices. Does the 379L-BE handle that, or do I need something else?
Trim is per leaf, so you order a 379L-BE for each active leaf, handed correctly for that leaf. Rim devices on a pair also need a center latching point: a removable mullion such as the Detex 90 Series keyed removable mullion is the part that gives rim devices something to latch into on a pair with no fixed mullion.
14) Is there a keyless code-entry trim I can use instead of a blank escutcheon?
Yes, if you want outside access by code rather than free entry. The Von Duprin 379L-BE is a mechanical blank escutcheon with an always operable no-cylinder function. Keyless alternatives include the Lockey 115P heavy duty keyless passage lever panic trim, which fits doors 1 3/16 inch to 2 inch thick, the Lockey 285P keyless mechanical panic trim with lever handle in the same door thickness range, the BEST EXZ electronic keypad exit device trim with key override, and the Dormakaba E-Plex E5010 electronic push button lever trim with key override, a Grade 1 trim for doors 1-3/8 inch to 2-1/4 inch thick.
15) For a pull-only exit door, is the 379L-BE or a dummy lever trim the better choice?
Both leave the door without outside key control. The Von Duprin 379L-BE is a Grade 1 heavy duty blank escutcheon with an always operable no-cylinder function, ordered with a lever design and handed RHR or LHR for 55 Series rim devices. The Corbin Russwin x650ET is a Grade 1 heavy duty dummy function lever trim with rose for ED7000 Series devices, where the lever is fixed and does not retract the latch. Choose by which device chassis is on the door and whether you want an operable lever or a rigid one.
16) Can I use the 379L-BE on an electric latch retraction exit device?
The Von Duprin 379L-BE is a mechanical blank escutcheon trim for Von Duprin 55 Series rim exit devices. Electrified latch retraction is a function of the device itself, not the trim - for example the ACSI ED4200-W036 is a Grade 1 wide stile rim exit device for the Corbin Russwin ED4000 Series with 24 volt AC/DC electric latch retraction. Match the trim to the device family you are actually installing.
