2. Select the dimensions from above which apply to the
roller latching arrangement to be installed.
NOTE: Door catch supplied with all disconnects is not
to be used with these door hardware kits.
3. Locate holes in door to secure handle assembly.
4. Determine Dimensions “BA” and “AV” to locate
locking bar guide bracket(s).
5. Locate door catch using “P” and “T” dimensions.
Location varies with each hardware kit. On 1494F-L4
and 1494F-LL4 hardware kits, attach the adjustable
catch after the support bracket is located. NOTE: Door
catch and guide bracket(s) are made with projections
for welding to the enclosure door. However, if a
specific installation permits, holes can be drilled in
the door catch and guide bracket(s) using the projec-
tions as centers. Then, after proper location and
using them as templates, corresponding holes can
be drilled in the enclosure door. Door catch and
guide bracket(s) are then fastened to the enclosure
door with hardware furnished by user.
6. Establish the length of the top locking bar by measur-
ing Dimension “AX” and subtracting

measuring Dimension “BE” and subtracting 3/4" for
Kits L2 and LL2; subtract 1

and LL2; add 3%” for Kits L4 and LL4. Locate, drill,
and tap holes where necessary. NOTE: These stan-

with these kits.
