The “OS” suffix option available for M68 series locks provides a modified “Offset” strike to shift
the strike contact face 1/4” [6.4mm] further away from the door frame stop than the standard
strike. This can be helpful in the installation to aluminum frame glass doors where the height of
the aluminum rail at the top of the door is not sufficiently wide enough to accommodate the
standard sex bolt/strike installation. It should be noted that an approximate 10% loss in holding
force results from the use of this strike because of its offset position however, this should not be
significant in that aluminum frame glass doors are not high security barriers. The offset strike is
included with locks ordered with the “OS” suffix or may be ordered separately.
A “Split Strike” configuration option is available for M68 series locks ordered with the “SS”
suffix. This allows one lock to be used to secure two doors in a double door configuration. In
this method, a single Magnalock is mounted near the center of the header and a half size strike
is provided for mounting to each door/leaf. This arrangement will also reduce the holding force
to about 550 Lbs. (250Kg) per door/leaf. Locks ordered with the “SS” suffix include the two
(split) strikes or they may be supplied separately.
7. MAINTENANCE
To keep the Magnalock in top working order, especially a Magnalock equipped with the “S”
(Senstat) option, we recommend taking a clean cloth and rubbing alcohol or a non-abrasive
cleaner and wiping down the face of the Magnalock and the strike once every six months.
