f you’re heavy-handed with the air sentry hatch on your Stryker, damaged hinges
could be in your future!
On vehicles with slat armor, the edge of the hatch hits the armor instead of the
rubber cushion that’s designed to absorb the blow. If you let the hatch fall open,
the hit can be violent enough to crack or break the hinge springs on the hatch. Not
only is opening and closing the hatch a lot harder, but the hatch surface can be
damaged, too.
Hold onto the latch when opening the air sentry hatch. Then gently lower the hatch
down against the slat armor.
Once the hatch is open,
you want it to stay that way
until you’re ready to close
it. Big bumps on the road or
explosions from improvised
explosive
devices
(IEDs)
can throw the hatch closed,
crushing anyone standing in
the hatch opening. Use the
lock mechanism to keep the
hatch safely open.
