NOTE: Specify push-bar operators in lieu of rotary
hand crank operation wherever feasible. Experience
indicates that rotary hand cranks require excessive
maintenance and, in most cases, will not withstand
continued hard usage. In the event push-bar
operation is not feasible, specify removable
crankhandles. Remote and group operation of windows
may require rotary crankhandle operation. See
paragraph "Special Operators."
