• Adjustable spring power: Size 1 (Barrier-Free) to Size 4 (Regular)
• Can retrofit existing fixed-spring closers
• Standard and extended spindle models
• 5 Year Limited Warranty

This CRL Jackson® Adjustable Spring Power Overhead Concealed Closer Body (SKU: 20101M19) is an adjustable spring power overhead concealed closer body that, depending on selected spring size and function, fits doors 30" to 42" (762 mm to 1.07 m) wide. It includes dual-action valves to set separate closing and latching speeds and offers 90° no-hold-open operation with multi-size adjustable spring power. Designed to fit standard 1-3/4" x 4" (45 x 102 mm) or larger header extrusions, this unit is interchangeable with Jackson® and similar overhead concealed closers—ideal for retrofit projects and replacements.

While the closer can be adjusted for site conditions, meeting A.D.A. maximum opening-force limits may prevent obtaining adequate closing force for some door sizes and applications.

Closers adjusted to comply with A.D.A. opening-force specifications may not provide sufficient spring power to reliably control and close the door under all conditions. Mounting clips are not included—use existing clips or purchase the appropriate Mounting Clip Package for your application. For help selecting the correct clip package, contact Jackson® Technical Sales.

Key differentiators: multi-size adjustable spring power, retrofit compatibility with fixed-spring closers, dual-action speed control, and interchangeable design for easy replacement.
