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.
4Adjust Bottom Latch Retraction (if necessary).
For 2-Point Latch Only
d. While holding the snap-fitting
with a ³⁄₈" wrench, continue to
tighten the locknut until it is
secure.
c. While holding the conduit cap
with a ³⁄₈" wrench, use a 10mm
wrench to turn the locknut in a
clockwise direction to close the
gap between the lock nut and
snap-fitting. Stop when the gap
is closed and the snap-fitting
begins to turn with the locknut.
a. While holding the snap-fitting
with a ³⁄₈" wrench, use a 10mm
wrench to break loose the lock
nut.
b. While holding the lock nut in
place, rotate the barrel of the
snap-fitting clockwise by hand
until the bottom latch is
retracted to within ¹⁄₁₆" of flush.
