CRL Jackson® Concealed 90° Closer, Adj Spring, No Hold-Open, 7/8" Ext

• 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: 20104M19) is engineered for A.D.A. barrier-free door applications and glass-door hardware. It includes a 7/8" extended spindle—preferred for use with Patch Fittings or Rail Hardware on frameless glass doors. The closer’s spring power is adjustable from size 2 through 4 using Patented Dual Compression Technology for finer tension control and improved spring efficiency. Fully independent valves deliver maximum adjustability to balance building codes, stack pressure and reliable door closure. Designed to retrofit most fixed-spring overhead concealed closers, it’s a professional-grade choice for installers and glazing contractors.


A.D.A. NOTE: Although the Adjustable Spring Power Door Closer can be adjusted to compensate for site conditions, adequate closing force might not be obtained while complying with A.D.A. opening force requirements.


Product Warning:

Closers set to comply with A.D.A. specified opening forces might not provide adequate spring power to control and close the door due to varying site conditions and door size. Mounting clips are not included; unless you reuse existing clips you must purchase the appropriate clip package for your application. Contact Jackson® Technical Sales for assistance selecting the correct Mounting Clip Package.
