General Lock CX3700-OH-105-NHO-S Adjustable Power Overhead Concealed Door Closer Kit (105° Stop)
General Lock CX3700-OH-105-NHO-S Adjustable Power Overhead Concealed Door Closer Kit (105° Stop)
The General Lock CX3700-OH-105-NHO-S is a complete, heavy-duty Overhead Concealed (OHC) Door Closer Package designed for reliable door control in high-traffic environments. Hidden entirely inside the frame header transom, this overhead concealed closer eliminates the bulky look of surface-mounted units.
This comprehensive kit comes fully loaded, including the heavy-duty cast iron closer body, specialized mounting hardware, and a Side Load Arm. Features an adjustable Size 1-4 spring strength and a built-in 105° non-hold-open function. The non-hold open (NHO) configuration ensures the door automatically closes after each use, making it ideal for applications where doors should remain closed for security, fire safety, or environmental control.
Adjustable spring power sizing from 1 to 4, customizable to accommodate a wide range of door sizes and opening requirements. The CX3700 series helps reduce door slamming, minimize wear on door hardware, and improve overall door control.
