Norton 1603BC-689 Door Closer

The Norton 1603BC-689 is a hydraulic door closer with a size #3 spring designed for standard commercial doors. It suits aluminum storefront entrances where reliable, automatic closing is required. The non-handed design works for both left and right swinging doors.

Hydraulic Valve Adjustment Limits

Three independent valves control sweep speed, latch speed, and backcheck intensity for precise tuning. Adjustments can be made at any time after installation to match site conditions. The rack and pinion mechanism with all-temperature hydraulics maintains consistent operation across seasonal changes.

Tri-Style Mounting Flexibility

Tri-Style packaging includes arms for regular, top jamb, and parallel arm mounting on a single template. The 73 mm projection fits common frame depths without interference. Standard arm applications allow 180-degree door swing where conditions permit. Compatibility with Parker 500, 950 and Yale 50 templates simplifies retrofit jobs.

Questions about this item

Which size spring does the 1603BC-689 use?

This closer is built with a sized #3 spring, which suits typical commercial doors and is not adjustable to other spring strengths.

What does the 180° swing rating mean for daily use?

With standard arm mounting the door can open a full 180 degrees, conditions permitting, giving maximum clearance for traffic and equipment.

How do the three valves control the closing action?

Separate valves adjust sweep speed, latch speed and backcheck intensity independently so you can tune each phase of the closing cycle on site.
