CRL 20101M18 Jackson Adjustable Spring Power Multi Size Hold-Open Overhead Concealed Closer Body

PRODUCT DESCRIPTION Jackson Overhead Concealed Door Closers (OHC) are available from C.R. Laurence as closer bodies only or as standard packages for center hung and offset door installations. The standard packages include the closer mechanism, mounting brackets, arms, and pivots. OHC's are divided into three groups: Standard OHC's (Brown) are offered with four (4) fixed spring sizes for doors from 2'6" to 4'0" wide (see chart on page 14). Other options include 90 degree and 105 degree hold open and non-hold open versions. Grade 1 OHC's (Black) have been tested to ANSI Grade 1 Standards (2 million cycles). They feature a valve adjustable hydraulic backcheck and are available in 90 degree and 105 degree hold open and non-hold open models. Adjustable OHC's (Blue) allow the opening spring force to be adjusted from 4.5 lbs. to 15 lbs. Adjustability is especially useful when attempting to balance between stack pressure and ADA requirements. The standard factory adjusted spring pressure is set to the size "Light Duty" and is intended for a 7'0" x 3'0" door. To increase the spring force by one size, turn the adjustment screw four (4) turns clockwise. Adjustable OHC's are also available in 90 degree and 105 degree hold open and non-hold open models. All Jackson OHC's are non-handed, double-acting, and work with center hung and offset applications. Additionally, the body size and mounting holes of standard and adjustable OHC's are identical and interchangeable with one another.

This CRL Jackson® Adjustable Spring Power Overhead Concealed Closer Body, which depending on the selected spring size and closer function, is suitable for a range of doors from 30" to 42" (762 mm to 1.07 m) wide. The closer features dual action valves for closing operation (one valve for closing, one valve for latching). 90º and 105º Hold Open and No Hold Open models are available. Closers fit into standard 1-3/4" x 4" (45 x 102 mm) or larger header extrusions. Interchangeable with all Jackson® and similar style of Overhead Concealed Closers.
