Built for demanding commercial and institutional openings, the HES Folger Adam 310-2 3/4 24D Electric Strike delivers industrial-grade strength and dependable electrified access control.

This configuration is specifically designed for locksets with up to a 3/4" throw latchbolt without a deadbolt. The strike features a 3/4" keeper, heavy-duty stainless-steel construction, horizontal keeper adjustment, and a 24VDC continuous-duty solenoid.

Designed for use on single doors or pairs of doors, the 310 Series is an excellent choice for high-traffic facilities requiring a rugged, fire-rated electric strike.

3/4" Latchbolt Configuration

The 310-2 3/4 configuration is specifically designed for locks with a latchbolt measuring up to 3/4" throw.

Unlike the standard 310-2 configuration, which uses a shallower keeper for shorter latchbolts, this version provides a 3/4" keeper for larger commercial latchbolt applications.

Designed For

• Up to 3/4" latchbolt throw

• Locksets without a deadbolt

• Single-door applications

• Pairs of doors with compatible hardware

24D – 24VDC Operation

The 24D designation indicates a 24 Volt DC electric strike.

Electrical Specifications:

• Voltage: 24VDC

• Current Draw: Approximately 250 mA

• Duty: Continuous Duty

A properly sized and regulated access-control power supply should be used.

Heavy-Duty Construction

The Folger Adam 310 Series is engineered for demanding openings where conventional light-duty electric strikes may not provide sufficient durability.

Performance specifications include:

Static Strength: 1,500 lbs
Dynamic Strength: 70 ft-lbs
Endurance: 1,000,000 Cycles

The strike is constructed entirely from stainless steel for strength, durability, and corrosion resistance.

Adjustable Keeper

The horizontally adjustable keeper allows the installer to compensate for minor door and frame alignment issues.

This adjustment can help achieve proper latch engagement without unnecessary modification to the existing opening.

Fail-Secure Operation

Standard 310 Series strikes are supplied fail secure unless the optional fail-safe configuration is specifically ordered.

With fail-secure operation:

• The strike remains locked when power is removed.

• Applying power releases the keeper for authorized access.

This is commonly used for commercial access-control applications where the opening must remain secure during a loss of electrical power.

Certifications

• ANSI/BHMA A156.31 Grade 1

• UL 10C Fire Rated

• UL 294 Listed

• UL 1034 Burglary-Resistant Listed

• RoHS Compliant

Typical Applications

• Commercial office buildings

• Hospitals and healthcare facilities

• Schools and universities

• Government facilities

• Detention and institutional facilities

• Industrial facilities

• Warehouses

• Controlled-access entrances

• High-traffic commercial doors

Important Ordering Information

This listing is for the 310-2 3/4 configuration, which is intended for a lockset with up to a 3/4" latchbolt throw and no deadbolt.

If the opening uses both a latchbolt and deadbolt, a different 310 Series configuration may be required.

The 24D designation specifies 24VDC and does not indicate the architectural finish.

Verify the required before opening:

• Latchbolt throw

• Voltage

• Fail-secure or fail-safe function

• Architectural finish

• Monitoring options

• Door and frame application
