Product Description
Von Duprin 6225 Electric Strike — Satin Brass
The Von Duprin 6225 combines open-back design with dual latchbolt monitoring. Built for thicker doors (1-3/4" to 2-1/4") where you need both extended-throw clearance and dual-signal confirmation. Factory configured as fail safe — power cuts, strike releases. 24VDC operation. Fire rated UL 10C. The most feature-packed strike in the 6200 line — open back, dual monitoring, and adjustable depth in one unit.
⚡ Fail Safe vs. Fail Secure — What's the Difference?
Fail Safe — Strike unlocks when power is lost. The door can be opened freely during a power outage. Required on most fire-rated egress doors for life safety. This is the default for fire exits and emergency egress paths.
Fail Secure — Strike remains locked when power is lost. Key override is always available from outside. Used for server rooms, evidence rooms, or anywhere security must be maintained during a power failure. The mechanical push bar still allows free egress from inside.
Pro-Tip from Our Locksmiths: This is a 24VDC model — make sure your power supply matches. Von Duprin PS914 or PS904 are the go-to supplies for 24V strike installations.
