Von Duprin VON-379L-626 – Frequently Asked Questions
1) What is the Von Duprin 379L Key Unlocks Trim used for?
The 379L is a key unlocks trim for Von Duprin 55 series rim exit devices. It allows key unlocking from the outside while maintaining free egress from the inside. The trim mounts on the outside of the door.
2) Which Von Duprin exit devices is this trim compatible with?
This trim is specifically designed for Von Duprin 55 series rim exit devices. It will not work with other series like 33, 88, or 99. Verify your exit device model before ordering.
3) Does this trim come with the cylinder and keys?
The 379L trim typically does not include the cylinder or keys. You need to order a compatible cylinder separately. Most standard mortise cylinders will work with proper threading.
4) What door handing options are available?
The 379L trim is available for both left-hand and right-hand doors. Specify the handing when ordering. Handing is determined by standing on the outside of the door looking at the hinges.
5) What finishes are available for this trim?
Common finishes include aluminum, dark bronze, and stainless steel. The finish should match your exit device and door hardware. Confirm available finishes when ordering as options may vary.
6) Can this trim be used on fire-rated doors?
Yes, when properly installed with a fire-rated Von Duprin 55 series exit device, this trim maintains the fire rating. Follow manufacturer installation instructions and local fire codes.
7) What tools are needed for installation?
Installation typically requires a drill, appropriate drill bits, screwdriver, and measuring tools. Follow the manufacturer's template for precise hole placement. Some door preparation may be needed.
8) How do you adjust the trim after installation?
The 379L trim has limited adjustment capability. Proper installation using the manufacturer's template is critical. If adjustment is needed, check mounting screws and verify door alignment first.
9) What are common installation issues to avoid?
Common issues include incorrect hole placement, wrong handing, and cylinder binding. Always use the manufacturer's template and verify measurements twice before drilling. Check door thickness requirements.
10) Are there alternative trim options for the 55 series?
Yes, Von Duprin offers other trim options for 55 series devices including lever trims and different cylinder types. The 379L is specifically for key unlocks function without lever operation.
11) What door thickness range does this trim accommodate?
Standard door thickness compatibility varies by trim configuration. Check manufacturer specifications for your specific installation. Most commercial doors from 1-3/4" to 2-1/4" thick are typically supported.
12) How does the key unlocks function work?
The key unlocks trim allows a key to retract the exit device latchbolt from outside. Inside egress remains free at all times by pressing the pushbar. This provides controlled access while maintaining emergency exit capability.
