CRL Jackson® Adjustable Spring Power Overhead Concealed Closer Body (SKU: 20106M18) is an adjustable overhead concealed door closer engineered for ADA barrier-free entrances and glass doors using patch fittings or rail hardware. The extra-long 1-13/64" spindle gives added "bite" for secure engagement. Patented Dual Compression Technology enables finer spring tension adjustment across sizes 2–4 for improved spring efficiency. Independent hydraulic valves provide precise control for sweep and latch speeds, helping balance building codes, stack pressure, and reliable door closure. Retrofits most fixed-spring overhead concealed closers and is widely specified by professionals.

Product Warning:
Closers set to comply with ADA-specified opening forces might not provide adequate spring power to control and close the door under varying site conditions or larger door sizes. Mounting clips are not included; reuse existing clips or purchase the appropriate mounting clip package for your application. Contact Jackson® Technical Sales for assistance selecting the correct mounting clip package.
