Description
The Norton 7500 Series is a heavy-duty surface-mounted door closer designed for interior and exterior doors in commercial facilities requiring reliable performance. Non-handed design works on either hand, with rack-and-pinion construction rated for over 25 million cycles. Independent valves control latch speed, sweep speed, and backcheck intensity for precise door operation in extreme temperatures from -40°F to high heat.
This size 690 closer (42-48 frame) mounts directly to the door surface with minimal projection. All external components are aluminum, brass, or stainless steel for corrosion resistance. Spring power adjusts from size 1-6 via hex key. For compatibility verification, proper sizing, and installation guidance, contact E.D.
