Authorized Online Dealer — Full Line of Trine Electric Strikes with Expert Support from Lock Depot Inc
Trine Access Technology is an American manufacturer of electric strikes used in commercial access control, institutional facilities, and gate entry systems. Trine strikes are known for their durability, wide voltage compatibility (most operate on 12V to 24V AC/DC), and practical design features that simplify installation. Their product line covers everything from compact cylindrical lock strikes to heavy-duty fire-rated solutions and outdoor-rated gate strikes.
Choosing the right Trine electric strike depends on your lock type, door frame, fire rating requirements, and whether the installation is indoor or outdoor. Here is a comparison of the most popular Trine series:
| Series | Application | Holding Force | Voltage | Fire Rated | Best For |
|---|---|---|---|---|---|
| 3234 (3000 Series) | Cylindrical locks | 1,200 lbs | 12-24V AC/DC | No | Light to medium duty interior doors |
| 4100 | Mortise & cylindrical | 3,250+ lbs | 12-24V AC/DC | Yes (3-hour) | Most commercial doors — the “one box solution” |
| 4200 | Cylindrical locks & deadlatches | 3,250+ lbs | 12-24V AC/DC | No | Door sag issues, alignment problems |
| 4800 | Surface-mounted rim panic | 3,000+ lbs | 11-28V AC/DC | Yes (4800F) | Rim panic exit devices, retrofit |
| EN400 / EN Series | Cylindrical, mortise, rim panic | 1,500+ lbs | 12-24V AC/DC | Yes (EN400) | Outdoor gates, fences, high-humidity |
The Trine 4100 is what we recommend for the majority of commercial access control installations. It is a Grade 1, 3-hour fire-rated electric strike that works with both mortise and cylindrical locksets. With a 1-3/8" shallow backset, it fits 2" fire-rated frames even with 1/2" sheetrock ingress. It ships with four popular faceplates covering over 90% of lock configurations, plus a CCTS (Cover Conversion Trim Skirt) for retrofitting HES 1006, Folger Adams 712/732, Von Duprin 6200, or Trine EN series strikes. Low 0.240A draw at 12VDC makes it PoE friendly. Over 1,000,000 life cycles and 3,250+ lbs of holding force.
The Trine 4200 features a tall 2-3/16" latch cavity specifically designed to solve door sag and alignment problems that plague many installations. It also solves auxiliary latch pin issues that other strikes have trouble with. Includes four faceplates for cylindrical locks and deadlatches, plus a trim skirt to cover gaps. Same low 0.240A current draw and 12-24V AC/DC operation as the 4100.
The 4800 series is purpose-built for surface-mounted rim panic exit devices. The completely open cavity allows a full 3/4" depth and up to 1" throw — more than competitor backplates offer. Grade 1 rated with 1,500,000+ life cycles and 3,000+ lbs holding force. Built-in electronics accept 11-28V AC/DC with surge and kickback protection. Trine’s patented 4-pin anchoring system ensures solid mounting.
For any outdoor application — gates, fences, marinas, pool enclosures, or any high-humidity environment — the Trine EN series is the correct choice. The EN400 is UL outdoor-rated and available with a gatebox for post mounting. The EN400CMRP is the most complete outdoor solution, working with cylindrical, mortise, and rim panic devices in a single unit. The EN800 handles rim panic devices specifically in outdoor settings.
Most Trine electric strikes operate on 12V to 24V AC or DC, giving you flexibility to use existing power supplies or PoE systems. The 4800 series has an even wider range of 11V to 28V AC/DC. The low current draw (as low as 0.240 amps at 12VDC on the 4100 and 4200) makes many Trine strikes compatible with Power over Ethernet installations. Always verify voltage requirements for your specific model before installation.
The Trine 4100 is a fire-rated (3-hour) electric strike for both mortise and cylindrical locks, making it the go-to for most commercial installations. The 4200 is designed specifically for cylindrical locks and deadlatches, with a taller 2-3/16 inch latch cavity that solves door sag and alignment problems. If you need fire rating or mortise lock compatibility, choose the 4100. If your door has sag issues or auxiliary latch pin problems, the 4200 is the better choice.
For outdoor gate and fence installations, use the Trine EN series. The EN400 is UL outdoor-rated, fire-rated, and available with a gatebox for mounting on posts. The EN400CMRP is the most versatile outdoor option, compatible with cylindrical locksets, mortise locks, and rim panic devices. For rim panic exit devices on gates, the EN800 is purpose-built for outdoor use. These models are designed to handle rain, humidity, temperature swings, and the heavy use that gates experience.
Yes. The Trine 4100 ships with a Cover Conversion Trim Skirt (CCTS) specifically designed for retrofitting the HES 1006, Folger Adams 712/732, Von Duprin 6200 Series, and older Trine EN Series strikes. The CCTS covers the existing cutout so you do not need to modify the door frame. This makes the 4100 a direct retrofit solution for the most common electric strike models on the market.
Trine line conditioners protect your electric strike from voltage spikes and electrical noise that can damage the solenoid over time. The LC100 is designed for single strike installations and the LC200 handles higher capacity needs. If your strike is powered from a shared electrical panel, is on a long wire run (over 50 feet), or is in an environment with electrical interference from motors or fluorescent lighting, a line conditioner is strongly recommended. It is inexpensive insurance for the life of your strike.
Trine electric strike holding force varies by series. The 4100 and 4200 exceed 3,250 lbs of static holding force. The 4800 series exceeds 3,000 lbs. The 3000 series (including the 3234) provides 1,200 lbs, suitable for light to medium duty applications. The EN400 provides over 1,500 lbs. All are tested to ANSI/BHMA Grade 1 specifications.
