These Closer-Holders are surface mounted to the Push (stop)
side frame face. The standard mounting for these units requires a minimum ceiling
clearance of 3-1/2" (89mm). Where ceiling clearance is between 2" and
3-1/2" (51mm and 89mm), the standard backplate for the 7220 Series or 7230 Series can
be inverted to allow for a drop application. Use a No. 7298 decorative backplate
is recommended to conceal the exposed mounting holes on the standard backplate. Different
mounting dimensions are required for the drop application. The double lever arm mounts
directly to the door. These units can be installed to accommodate door openings to 180°
with a 170° maximum hold/open point.
The Series 7220MPI/7230MPI and 7220MPS/7230MPS, with double
lever arm, are intended for use with compatible U.L. listed detection equipment.
