Adjustable Spring Power Size 1 (Barrier-Free) to Size 4 (Regular)
Can Retrofit Existing Fixed Spring Closers
Extended Spindle Models Only

This adjustable spring power overhead concealed closer body is designed for A.D.A. barrier-free applications and features a 7/8" extended spindle, the preferred length when used in conjunction with patch fittings or rail hardware on all glass doors. Its spring power is adjustable from a size 2 through 4 using dual compression technology providing finer spring tension adjustment and greater spring efficiency. With fully independent valves, this closer affords maximum adjustability when trying to balance building codes, stack pressure and keeping the door closed. It will easily retrofit most all fixed spring size overhead concealed closers.
