to the enclosure door. However, if a specific installa-

tion permits, holes can be drilled in the door catch and

guide bracket(s) using the projections 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 fas-

tened to the enclosure door with hardware furnished

by user.

6. Establish the length of the top locking bar by meas-

uring Dimensions “E” and subtracting 3/4" for Kits L1

and L2; subtract 1-1/8" for Kit L4. Determine the

ength of the bottom locking bar by measuring Dimen-

sion “K” and subtracting 3/4" for Kit L2; subtract

l-l/8" for Kit L4. Dimension “H” is determined by

measuring Dimension “D” and adding 3-3/4" for Kits

L1 and L2; add 3-5/8" for Kit L4. Locate, drill, and

tap holes where necessary. NOTE: These standard mill

rectangular locking bars are not supplied with these

kits.

7. The door locking hardware assembly can now be at-

tached to the door.

INSTRUCTIONS

Check all minimum enclosure and door dimensions

required for installation. Refer to Page 1 and above.

2. Select the dimensions from above which apply to the

roller latching arrangement to be installed.

NOTE: Door catch supplied with operating mechanism

is not to be used with these door hardware kits.

3. Locate holes in door to secure handle assembly.

4. Determine Dimensions “B” and “C” to locate locking

bar guide bracket(s).

5. Locate door catch using “P” and “T” dimensions. Lo-

cation varies with each hardware kit. On 1494F-L4

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
