KEYED REMOVABLE
MULLION
Engineered as the ultimate security
partner for both series 3700 Rim
and 3600 Concealed Vertical Rod
devices, these keyed removable
mullions provide a sturdy and secure
latching point.
With one easy turn of a key the
mullion can be removed to allow
the full width of a door opening to
be available. Reinstallation of the
mullion is just as easy: just snap the
mullion back into the secure mount
on the top of the door frame.
No key is required to reinstall.
Easily cut for a perfect field fit,
these mullions come with heavy
duty stainless steel strikes and are
available in sizes up to 9 feet.
Color matched security clips provide
an added level of security by
overcoming the natural twisting of
the door stile under pressure.
