Typical Lifespan Factors
Sargent does not provide a specific cycle rating for this individual small component, but general commercial hardware standards suggest a lifespan that can be calculated based on the building's traffic.
- High-Traffic Areas (e.g., schools, hospitals, busy office buildings): In areas where a door might be opened 50+ times a day, this spring may need replacement every 2 to 5 years. Springs in these environments wear down faster due to constant metal fatigue and usage cycles.
- Normal Commercial Use (e.g., standard office entry): With average use of around 10-20 cycles per day, the spring can reliably last for 5 to 10 years.
- Overall Device Warranty: The exit devices this spring fits into typically carry a multi-year warranty (often 3 to 5 years), suggesting a baseline expected performance for all internal components within that period under normal operating conditions.
Signs It Needs Replacement
The lifespan is ultimately determined by the spring's failure, indicated by specific signs:
- The latch bolt no longer fully extends when the door is open.
- The door fails to fully latch when closed (known as "latch drag").
- The mechanism feels "loose" or lacks positive spring tension.
