This CRL Jackson® Adjustable Spring Power Overhead Concealed Closer Body (SKU: 20104M17) is engineered for A.D.A. barrier-free applications and glass door hardware. The preferred 7/8" extended spindle works with patch fittings and rail hardware on glass doors. Spring power adjusts from Size 2 through Size 4 using Patented Dual Compression Technology for finer spring tension and greater efficiency. Fully independent valves allow precise balancing of closing speed, latch, and stack pressure. Designed to retrofit most fixed-spring overhead concealed closers, this adjustable concealed door closer is a professional-grade choice for commercial glass doors and A.D.A.-sensitive installations.

A.D.A. NOTE: Although the adjustable closer can be tuned for site conditions, adequate closing force may not be obtainable while also meeting A.D.A. opening force limits.

Product Warning:

Closers set to meet A.D.A. opening force requirements may not provide sufficient spring power to control and close the door under varying site conditions and door sizes. Mounting clips are not included; use existing clips or purchase the appropriate clip package. Contact Jackson® Technical Sales for assistance selecting the correct mounting clip package.
