Product Description
V40W LD 628 99 36 Detex V40 Series Rim Exit Device — Less Dogging, Satin Aluminum Clear Anodized
Fire-rated openings don't allow dogging — the door must latch positively every single time. The Detex V40W is purpose-built for fire-rated exits where code prohibits any hold-open mechanism.
Weatherized model — designed for exterior doors exposed to rain, snow, humidity, and temperature extremes. Sealed components prevent corrosion and alarm circuit failure.

Pro-Installer FAQ
Can this device be cut down for narrower doors?
Yes, the pushbar can be field-cut for doors narrower than standard width. Measure carefully and cut from the hinge end only. The lock stile end must remain factory length for proper strike engagement.
Why would I choose Less Dogging?
LD (Less Dogging) is required on fire-rated door openings where code prohibits holding the latch open. Even if the device itself isn't fire-rated, the opening may require LD based on the door's fire label.
Does Detex cover this under warranty?
Detex provides a limited lifetime warranty on mechanical components and 3 years on electronic components. This covers manufacturing defects — not field damage or improper installation.
