Equip demanding commercial openings with the HES Folger Adam 310-2-24D-630 Electric Strike, an industrial-grade access-control solution engineered for extreme heavy-duty applications.

The Folger Adam 310 Series features an all-stainless-steel construction, high-strength keeper assembly, and commercial-grade solenoid designed to withstand abusive, high-cycle environments that can quickly wear out conventional electric strikes.

This exact configuration features a 1/2" keeper, 24VDC operation, and 630 Satin Stainless Steel finish. It is designed for compatible cylindrical and mortise locksets with latchbolts up to 5/8" throw.

The 310 Series is ANSI/BHMA Grade 1 and carries a 3-hour fire rating when used in fail-secure operation.

310-2 Keeper Configuration

The 310-2 is supplied with a:

1/2" Keeper

This configuration accommodates compatible cylindrical and mortise locksets with latchbolts measuring up to approximately:

5/8" Throw

For locks using a larger 3/4" latchbolt, HES offers the separate 310-2-3/4 configuration.

Always verify the existing latchbolt throw before ordering.

24D – 24VDC Operation

The 24D designation specifies:

24 Volts DC

Approximate electrical requirement:

250mA @ 24VDC

The strike is designed for continuous-duty commercial access-control operation when connected to a properly sized and regulated power supply.

3-Hour Fire-Rated

The HES Folger Adam 310 Series is listed for up to a:

3-Hour Fire Rating

for both compatible single- and double-door applications when configured fail secure.

During loss of electrical power in the standard fail-secure configuration, the strike remains mechanically secure.

Fire-rated installations must follow the requirements of the strike listing, door and frame labeling, hardware manufacturer, applicable fire code, and Authority Having Jurisdiction.

Industrial-Grade Strength

The Folger Adam 310 Series is engineered for applications where heavy traffic, abuse, or high security requirements demand greater strength than a conventional electric strike.

Performance Ratings

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

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

Horizontal Keeper Adjustment

The keeper can be adjusted horizontally to compensate for minor door and frame alignment issues.

This feature can help:

• Improve latch engagement

• Compensate for door sag

• Correct minor frame misalignment

• Reduce binding

• Simplify final installation adjustment

Fail-Secure Operation

The standard 310-2 configuration is fail secure.

Fail Secure

• Strike remains locked when power is removed

• Applying power releases the keeper

• Commonly used for secured commercial openings

• Required configuration for maintaining the published 3-hour fire rating

Fail-safe configurations may be available, but the 3-hour fire rating applies to fail-secure operation.

Compatible Lock Applications

The 310-2 is designed for compatible:

• Cylindrical locksets

• Mortise locksets without incompatible deadbolt conditions

• Commercial access-control openings

• Single doors

• Compatible pairs of doors

Always verify the specific lockset and latchbolt geometry before ordering.
