Three Strike Families, Three Different Jobs
When an access control project calls for an electric strike, the choice between the HES 1006 series, Folger Adam heavy-duty strikes, and Adams Rite frame-mounted strikes is not a matter of preference -- it is a matter of matching the strike to the door type, locking hardware, and environment. This guide breaks down how each family works, where each one belongs, and what questions to answer before you order. It is aimed at commercial subcontractors, security integrators, and facility managers specifying or replacing electrified hardware on commercial, institutional, or industrial openings.
What Is an Electric Strike?
An electric strike replaces a conventional fixed strike plate in the door frame. Instead of requiring a key or credential at the lock itself, the strike releases its keeper electronically, allowing the latchbolt or deadlatch to swing free and the door to open -- while the lockset on the door remains mechanically unchanged. The lockset function (classroom, storeroom, or similar) still controls ingress when the strike is not energized; a passageway-function latchset defeats the access control entirely and should never be paired with an electric strike.
HES 1006 Series: The High-Strength Workhorse for Standard Frames
The HES 1006 is built around a dual interlocking plunger design in stainless steel construction. According to manufacturer documentation, it is rated at 2,500 lbs. static strength (fail secure), 350 ft-lbs. dynamic strength, and tested to exceed 1,000,000 cycles. Those numbers put it at the top of the ANSI 4-7/8 inch strike pocket category.
Where the 1006 Fits
- Hollow metal frames with cylindrical or mortise locksets -- the 1006 is non-handed and fits any standard ANSI 4-7/8 inch prep
- Deadbolt applications -- it accommodates up to a 1 inch deadbolt throw alongside the latchbolt
- Schools and healthcare corridors -- high cycle count and tamper-resistant construction suit high-traffic institutional openings
- Retrofits -- interchangeable faceplates let the installer match radius or square corners and adapt to most existing strike preps without cutting new mortises
Available Options
- Fail safe or fail secure (fail secure is standard)
- Latchbolt monitor (LBM) and latchbolt strike monitor (LBSM) for door-position or latch-position feedback to the access control panel
- Accessories: rain guard, full keeper shims, lip extension trim adapter, and replacement strike plate
The 1006 does not belong on a narrow-stile aluminum storefront door -- the frame geometry and latch type on those doors require a purpose-built solution.
Folger Adam: Heavy-Duty Strikes for Harsh and High-Security Environments
Folger Adam strikes are recognizable by their external solenoid -- a design that has been in the field for decades and remains intentionally serviceable. The external solenoid can often be replaced in the field without pulling the entire strike body, which matters in environments where downtime is costly.
Where Folger Adam Fits
- Industrial and high-hazard locations -- chemical plants, manufacturing floors, and pool areas where corrosive atmospheres accelerate wear on lighter-duty strikes
- Heavy steel frame applications with mortise locksets that demand a strike body built to match the frame mass
- Correctional and detention -- the sheer physical mass of a Folger Adam strike is an asset in forced-entry-resistant openings
- High-cycle security perimeters -- exterior doors in retail loss-prevention, industrial receiving, and similar contexts
Installation Realities
The external solenoid adds depth behind the frame, so rough-in clearance matters. In retrofit situations, verify that the solenoid orientation -- up or down -- is compatible with the frame pocket and adjacent hardware. The solenoid typically projects upward on steel frames; confirm with the frame shop if the rough-in is being cut to order.
Because of its mass and installation complexity, Folger Adam is not the first call for a routine office or school retrofit, but it is the right call when the environment would destroy a lighter-duty product within months.
Adams Rite 7100 and 7400 Series: Purpose-Built for Narrow-Stile Aluminum Doors
Adams Rite electric strikes occupy a completely different category. They are frame-mounted strikes engineered specifically for the narrow-stile aluminum and glass storefront doors that define retail entries, school vestibules, and commercial building lobbies. Conventional strikes do not fit these frames -- the stile geometry and Adams Rite deadlatch dimensions require a strike designed around that hardware family.
7100 vs. 7400 -- The Core Difference
- 7100 Series: Fixed voltage, fixed function, all fail secure. Available in 12VDC, 24VDC, and 24VAC. Economical and straightforward for standard aluminum storefront installs. Faceplate options include 4-7/8 inch and 6-7/8 inch flat face.
- 7400 Series (Preload): Designed for openings where spring tension presses the door hard against the strike -- a condition called preload -- that can cause standard strikes to resist releasing. The 7400 addresses preload directly and is available in both fail safe and fail secure. Fail safe is commonly required on egress paths by the AHJ.
Where Adams Rite Strikes Fit
- Aluminum storefront vestibules at schools, retail, and medical office buildings
- Glass door entries where the Adams Rite 4500 or 4900 deadlatch is the existing hardware
- Access-controlled lobbies paired with a keypad or card reader and a Fail Safe 7400 on the egress path
Side-by-Side: Which Strike for Which Opening?
- Hollow metal frame, cylindrical or mortise lockset, standard commercial or institutional use: HES 1006 series
- Industrial, chemical, pool, or high-security heavy steel frame with mortise lock: Folger Adam
- Narrow-stile aluminum storefront, Adams Rite deadlatch: Adams Rite 7100 (standard) or 7400 (preload or egress path requiring fail safe)
Monitor Switches and Access Control Integration
If your access control panel needs door-position or latch feedback, verify monitor switch availability before finalizing the strike model. The HES 1006 offers LBM and LBSM options; not all faceplate combinations are compatible with the monitor switch, so check the option matrix. Folger Adam and Adams Rite monitor options vary by model -- confirm with the integrator what signal type the panel expects (dry contact, normally open vs. normally closed) before specifying.
Get the Right Strike the First Time
Choosing the wrong electric strike for a frame type wastes budget, delays closeout, and can introduce a life-safety gap if a fail-safe or fail-secure designation is wrong for the egress path. DoorwaysPlus carries electric strikes across application categories and can help you match the right product to the opening before it ships.
