Trine 4100-32D Electric Strike for Cylindrical & Mortise

The Trine 4100-32D is a Grade 1, fail-secure electric strike with a satin stainless steel (BHMA 630) finish, over 3,250 lbs of holding force, and a 3-hour fire rating for compatible cylindrical and mortise locks without deadbolts. It features four interchangeable 4-7/8-inch faceplates, a shallow 1-3/8-inch backset, and 12/24 VDC or 12-24 VAC operation. Designed for commercial access control systems, the 4100-32D offers over 1 million operating cycles, UL 294 and UL 1034 listings, and a trim skirt for retrofit installations.

Trine 4100-32D Grade 1 Fire-Rated Electric Strike, Satin Stainless Steel

The Trine 4100-32D is a heavy-duty, Grade 1 electric door strike designed for cylindrical and mortise locksets without deadbolts in commercial and institutional access control applications. Part of the Trine 4100 Series, this fail-secure electric strike delivers over 3,250 lbs of holding force and a tested endurance of more than 1 million operating cycles, providing dependable electrically controlled door release for high-traffic openings. The strike incorporates Trine's One Box Solution, which includes four interchangeable faceplates to accommodate common cylindrical and mortise latch configurations without requiring separate faceplate purchases. Its satin stainless steel finish (US32D/BHMA 630) provides an architectural appearance suitable for commercial door hardware installations. In its standard fail-secure configuration, the strike remains locked when power is removed and releases the latch when electrical power is applied, allowing authorized access through compatible card readers, keypads, intercoms, and electronic access control systems.

The Trine 4100-32D supports 12 or 24 VDC and 12-24 VAC operation, providing flexibility for different electric locking power supplies and access control installations. According to Trine's current electrical specifications, the strike draws approximately 310 mA at 12 VDC or 140 mA at 24 VDC, with continuous-duty operation supported on DC power. Alternating-current operation is supported at 12, 16, or 24 VAC for intermittent-duty applications, producing an audible buzzing sound during activation, while DC operation provides silent release. The strike's low-current design supports integration with compatible networked access control and power distribution systems, subject to available supply current and wiring requirements. Its heavy-duty construction and Grade 1 classification make it suitable for commercial openings exposed to frequent operation, while the 3-hour fire-rated fail-secure configuration supports qualifying fire door assemblies when installed according to the applicable listing and manufacturer's instructions.

The 4100-32D features a 1-3/8-inch shallow backset and 3/4-inch cavity depth, reducing frame preparation requirements compared with deeper electric strike mechanisms. The package includes four 4-7/8-inch by 1-1/4-inch faceplates with CC, MHO, MMO, and MLO latch opening configurations, allowing installers to accommodate different latch positions and mortise lock designs. Trine specifies compatibility with more than 90% of common cylindrical and mortise lock configurations without deadbolts. The strike can be installed in compatible hollow metal or wood door frames, including certain 2-inch fire-rated frames with 1/2-inch drywall intrusion. Included latch spacer shims allow adjustment of latch alignment and help prevent binding between the door latch and electric strike keeper. The supplied matching stainless steel trim skirt conceals frame preparation gaps and supports retrofit installations replacing select HES 1006, Folger Adams 712/732, Von Duprin 6200 Series, and Trine EN Series electric strikes. Voltage-specific quick-connect assemblies, sealed crimp connectors, mounting screws, and installation hardware simplify wiring and installation.

The Trine 4100-32D is engineered for commercial offices, schools, healthcare facilities, warehouses, institutional buildings, and other access-controlled openings requiring a durable, fire-rated electric strike. The standard model is designed for fail-secure operation and is recognized for 3-hour fire-rated single-door and frame assemblies under UL 10C, with additional manufacturer-listed compliance references including UBC 7-2, CAN4-S104, and NFPA 252. The 4100 Series is also identified as UL 1034 burglary-resistant and UL 294 access control listed, with Grade 1 performance and frame preparation dimensions associated with ANSI/BHMA A156.5 and ANSI A115.1 requirements. The standard 4100-32D differs from the 4100RS-32D fail-safe configuration, which releases when power is removed and does not retain the manufacturer's fire listing. Optional configurations include the 4100LB latch bolt monitoring model and 4100RSLB fail-safe model with latch monitoring. Its combination of high holding strength, interchangeable faceplates, low-profile construction, flexible operating voltages, and satin stainless steel finish makes the Trine 4100-32D a versatile electric locking solution for new construction and retrofit access control applications.
