HANDING IDENTIFICATION
For MH and MHS models 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 illustration shown is a right-handed operator for
models MJ and MHS series only. Left-handed operator will have
hoist chain on the left side.
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. Output Shaft
