press

b. To determine whether an adjustment is required, actuate the top

latch to the hold-open position by pressing down on the connecting

rod. Bottom latch should retract to within ¹⁄₁₆" of flush. If it does not,

an adjustment is necessary.

If no adjustment is

needed, proceed

to Step 5.

4Adjust Bottom Latch Retraction (if necessary).

For 2-Point Latch Only

a. Pull back and hold the spring-loaded sleeve.

b. While holding the sleeve in place, rotate the barrel of the snap-fitting

clockwise by hand until the bottom latch is retracted to within ¹⁄₁₆" of

flush.

c. Slowly release the sleeve, confirming it has seated over the hex end of

the snap-fitting.

NOTE: Adjustment must be made while the top

latch is in the hold-open position, with cable

flexed into an L-shape to simulate the installed

condition of the latches.

These (2) hex

components

are used to

make the

adjustment.
