    Industrial-Grade Electric Strikes Built for Detention, Government & Healthcare

    If you've ever ripped out a lightweight electric strike that cracked after six months on a high-traffic stairwell door, you already know why Folger Adam exists. These are not standard commercial-grade strikes — Folger Adam electric strikes are engineered for the harshest environments in the industry: detention facilities, government buildings, hospitals, and any opening where failure is not an option. All stainless steel construction. 1,500 lbs static strength. 70 ft-lbs dynamic strength. A million-cycle endurance rating. This is the hardware you spec when the opening has to perform for decades, not months.

    Folger Adam is now part of the HES / ASSA ABLOY family, but the product line and quality haven't changed. The 310 Series is the flagship — a heavy-duty electric strike available in multiple configurations to match virtually any door and lock combination in a commercial or institutional building. The 310-2 handles standard cylindrical and mortise lock latchbolts. The 310-3-1 adds deadbolt capability with a full 1" keeper depth. Need to electrify vertical rod exit devices? The 310-4 covers surface-mounted rods and the 310-6 handles concealed vertical rods.

    One thing experienced installers appreciate about the 310: the horizontally adjustable keeper compensates for door-to-frame misalignment without shimming. On retrofit jobs where the frame isn't perfectly plumb anymore, that adjustability saves real time on the job site. And if you're dealing with preload issues from weather-swollen doors or positive-pressure HVAC systems, the 310's stainless steel construction handles binding forces that would chew up a lighter strike in weeks.

    Every model comes in Fail Secure or Fail Safe, 12VDC or 24VDC, with optional LCBMA latchbolt and locking cam monitoring for full access control integration. At Lock Depot, we stock the complete Folger Adam 310 Series catalog — strikes, keeper assemblies, solenoid replacements, and monitoring options. All products are brand new with the full manufacturer warranty. Order by 2 PM EST for same-day shipping.

    ⚠ LOCK DEPOT PRO TIP: When specifying a Folger Adam 310 for a mortise lock with deadbolt, make sure you're ordering the 310-3-1 with the 1" keeper — not the 310-2. The 310-2's half-inch keeper only handles the latchbolt throw. If you try to use it with a deadbolt that throws 3/4" or more, the bolt won't clear the keeper lip and you'll be back on site recutting the frame. Always match the keeper depth to the total bolt projection. Also check your voltage — all 310 Series are DC only. If your access control panel outputs AC, you'll need a rectifier or DC power supply before the strike.

    Folger Adam Electric Strike — Frequently Asked Questions

    Q: What is the difference between Folger Adam 310-2 and 310-3-1?
    A: The 310-2 has a 1/2" keeper depth designed for standard cylindrical and mortise lock latchbolts up to 5/8" throw. The 310-3-1 has a 1" keeper depth that accommodates both a 3/4" latchbolt and a 1" deadbolt. If your mortise lock has a deadbolt function, you need the 310-3-1.

    Q: Is the Folger Adam 310 Series fire rated?
    A: Yes. The entire 310 Series carries a 3-hour fire rating when properly installed in a fire-rated frame assembly. This makes it suitable for stairwell doors, corridor separations, and other fire-rated openings in commercial and institutional buildings.

    Q: What does LCBMA mean on Folger Adam electric strikes?
    A: LCBMA stands for Latchbolt and Locking Cam Monitor with Auxiliary switch. It provides two monitoring functions: the latchbolt monitor confirms the door is latched, and the locking cam monitor confirms the strike is in the locked position. This is essential for access control systems that need real-time door position feedback.

    Q: Can I use a Folger Adam 310 with a vertical rod exit device?
    A: Not the standard 310-2 or 310-3-1. For surface-mounted vertical rod exit devices (Von Duprin 98/99-series, for example), use the 310-4 Series. For concealed vertical rod exit devices, use the 310-6 Series. Both use a Pullman-type keeper assembly designed specifically for vertical rod latch configurations.

    Q: What voltage does the Folger Adam 310 require?
    A: All 310 Series strikes are available in 12VDC or 24VDC. DC power is standard — there is no AC option. If your access control panel outputs AC, you'll need a rectifier or DC power supply. Current draw is approximately 0.51 amps at the rated voltage.

    Q: Is Folger Adam the same as HES electric strikes?
    A: Folger Adam and HES are both part of the ASSA ABLOY family, but they serve different markets. HES strikes (like the popular 1006 Series) are designed for standard commercial applications. Folger Adam 310 Series strikes are built for industrial and institutional environments — detention, government, healthcare — where you need stainless steel construction, higher holding force, and million-cycle endurance.

    Q: How fast does Lock Depot ship Folger Adam orders?
    A: If the item is in stock and ordered by 2 PM EST, it ships the same day. We stock the full 310 Series catalog including all keeper configurations and monitoring options.
