About this item
The Trine 323478LC is a 3000 Series electric strike that lets you release a door electrically for access control while keeping it securely latched the rest of the time. An electric strike replaces the fixed strike plate on the door frame: when it's energized, the keeper pivots so the door can be pushed open without turning the handle, which is how a buzzer entry, card reader, or keypad releases the door. The 323478LC is fail secure (the door stays locked when power is lost), runs on 12 or 24 volts AC or DC, and ships with multiple faceplates and the 30LC mechanism so it fits a wide range of frames out of the box. It's a universal ANSI solution for cylindrical and similar latch applications.
What fail secure means and how the strike works
This is the key decision point on any electric strike, so it's worth being clear. Fail secure (also called fail locked) means the strike stays locked when it loses power, you need a key or a powered release to get in, but exit is always free from the inside. That's the right choice for most exterior and security doors, because a power outage leaves the door secured rather than open. The opposite, fail safe, unlocks on power loss for doors that must release in an emergency. Note one important code point: this strike's 3-hour fire rating applies in fail secure operation, the UL10C fire listing is void if the strike is converted to fail safe (RS).
When wired to an access control system, intercom, or release button, energizing the 323478LC frees the keeper so the door opens on a push, then it relatches automatically when the door closes.
Why the 323478LC fits so many doors
This is where Trine's design stands out, and it's the reason to choose this kit. The 323478LC includes three faceplates: the 234-26D (2-3/4 inch), the 234X-375-26D (2-3/4 inch with an extended ramp), and the 478-32D (4-7/8 inch ANSI), plus the 478-CCFP filler and the 30LC mechanism (11-29V AC and DC). That faceplate bundle means one part number covers wood or hollow metal frames and both narrow and standard ANSI prep, so you're not guessing which faceplate to order. Trine's patented horizontal adjustment lets you align the keeper to the latch precisely and locks it so it won't drift, and the 3000 Series is built around one of the smallest electric strike faceplates available, so it tucks into tight jambs and partitions. Trine also notes its faceplates need up to 60 percent less frame cutting than a standard strike plate (and the 234 up to 80 percent less), which saves real labor on installation.

Why choose the Trine 323478LC
Trine has specialized in electric strikes for decades, and the 323478LC is its universal 3000 Series solution: one kit, multiple faceplates, fail secure, fire rated, and Grade 1 heavy duty. The included faceplate range and small footprint make it a true do-it-all strike for retrofits and new installs, and the patented adjustment plus reduced frame cutting cut down install time and callbacks. For an access control project that needs a reliable, code-compliant strike that fits the frame you actually have, this kit covers the bases.
One thing to confirm before ordering: this is the fail secure version, which keeps the 3-hour fire rating. Verify your latch and frame prep match the included faceplates, and confirm your access control system supplies 12 or 24V AC or DC.
