CRL JACKSON OVERHEAD CONCEALED DOOR CLOSER
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) xed 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.

INSTRUCTIONS AND ADJUSTMENTS
IMPORTANT: PLEASE READ BEFORE PROCEEDING. Observe all safety warnings. Always wear proper eye
protection and appropriate safety equipment. Always place a safety block between the door and the jamb to prevent the
door from closing while making adjustments. The closer contains springs compressed under high load and has no user
serviceable internal components. Do not attempt to remove the covers or otherwise open the closer in any manner.
The closer has been fully tested and adjusted at the factory. The closing and latching speeds have been pre-set to achieve a
6 to 8 second closing cycle. The optional hydraulic backcheck has not been factory pre-set. After installation, cycle the door
10 or more times from the maximum open position to the full closed position prior to making nal adjustments.
To increase either the closing or latching speeds, turn the appropriate adjustment valve counter-clockwise. To decrease either
the closing or latching speeds, turn the appropriate adjustment valve clockwise. Set the latching speed (Valve "L") rst, then
set the closing speed (Valve "C"). Check and readjust if necessary.
Hydraulic Backcheck (if so equipped) turn the adjustment valve clockwise to increase backcheck resistance which dampens
and slows the momentum of the door when opened with excessive force. Decrease resistance by turning the adjustment valve
counter-clockwise. The adjustment valve must not be adjusted so that the backcheck function is used as a rigid backstop.
Using the backcheck as a rigid backstop may cause damage to the closer or door.
Adjustable Spring Power (if so equipped) the adjustable spring power has been factory set to Size 2. To increase the
spring power, turn the adjuster clockwise. To decrease, turn the adjuster counter-clockwise. Typical door opening force adjusts
at the rate of approximately 1 pound of force (4.5 N) for each 3 to 4 revolutions of the adjuster.
IMPORTANT: Do not attempt to adjust the spring power with the door open beyond 20 degrees from fully closed.
WARNING: Neither the standard internal back stop nor the optional backcheck are to be used as the primary door stop.
An auxiliary oor or overhead door stop is always recommended to prevent structural interference and possible door and
closer damage.
