Description
The Norton 8501 is a heavy-duty surface-mounted door closer designed for high-traffic commercial and institutional applications. Built with a cast aluminum body and rack-and-pinion mechanism, it delivers reliable performance exceeding 10 million cycles. Non-handed design works on doors of either hand, making it ideal for facilities managers and contractors seeking durable, low-maintenance closer solutions.
The 8501 mounts directly to the door surface with a full plastic cover standard. Compatible with interior and exterior doors, it features multi-size spring power adjustment (sizes 1-6), two independently adjustable valves for sweep and latch speeds, backcheck control, and optional delayed action closing. All adjustments use hex key tools for precise field tuning. As an authorized Norton dealer, E.D. Locks provides expert sizing and installation guidance.
