It is imperative that the wall or mounting surface provide
CAUTION
adequate support for the operator.
This surface must:
a. Be rigid to prevent play between operator and door shaft.
b. Provide a level base.
c. Permit the operator to be fastened securely and with the
drive shaft parallel to the door shaft.
The safety and wear of the operator will be adversely affected if
any of the above requirements are not met. For metal buildings,
fasten 2" x 2" x 3/16" (or larger) angle iron frames to the building
purlins. Retain 5-1/2" (13.97 cm) between frames.
Both J and H series operators have dual output shafts and may

in either a vertical (standard) or horizontal mounting position. If
you need to move the drive sprocket, loosen BOTH set screws,

the drive shaft. Be sure to tighten BOTH set screws securely.

HAND CHAIN HANDING

For models H and HJ with manual hoist hand chain systems, the
handing of the operator must be determined at the time of order.
The handing is indicated by last letter of the model name
(R or L). The hand chain wheel can not be switched on site. If
your installation causes the hand chain to hang in the door
opening, hook the chain off to the side near the top of the door
jamb.
