3.3 Lockbox Mortise
Determine the handle height to be used. The
Unitop Model 1455-3 lock comes with a
standard handle height of 1050 mm (41.34”).
Using this handle height will mean that no
cutting will need to be done on the lock
bottom. You may attain a handle height as
low as 748 mm (37.32”). See section 3.4.
Refer to the figures and mortise for lock box,
handle spindle, trim and profile cylinder
(optional).
Note: If a handle is not needed on the
exterior side make sure not to drill thru
for the spindle. If a full locking cylinder is
used drill thru. If a half locking cylinder is
used do not drill thru. If no locking
cylinder is used do not drill for it. Take
this into consideration for trim also.
