Folger Adam 003-0203-001 Latchbolt Keeper Spring — 300 Series Electric Strike Replacement Part

The Folger Adam 003-0203-001 is a genuine OEM replacement latchbolt keeper spring designed specifically for the Folger Adam 300 Series electric strike. Referenced as Part #6 in the 300 Series parts diagram, this small-but-critical component maintains the tension needed for the keeper to properly engage and release the door latchbolt during each access cycle.

When the keeper spring wears out or loses tension, the electric strike may fail to hold the door securely in the latched position — or may not release cleanly when energized. Replacing this spring restores reliable operation and extends the service life of the existing strike assembly, avoiding a costly full-unit replacement.

Key Benefits

• Genuine OEM part — manufactured to Folger Adam 300 Series tolerances for a precise, drop-in fit
• Restores proper keeper tension — ensures the latchbolt is held securely and releases cleanly on every access cycle
• Low-cost repair solution — part-level service keeps the full strike assembly in service
• Fast, field-serviceable installation — no special tools required for experienced technicians

Applications

• Preventive maintenance programs for commercial door hardware
• Field repair of Folger Adam 300 Series electric strikes showing keeper play or inconsistent latch engagement
• Facility managers and service technicians maintaining access-controlled openings with existing 300 Series hardware
• Replacement sourcing for commercial contractors and installers servicing institutional, healthcare, education, and office facilities
