ACCESS DOORS
Door Latches
Although maintenance of latches is not necessarily required, it is advisable to occasionally apply a light
oil to moveable parts to prevent binding.
Square Head Key Latches
Square head key latches are opened by inserting a 1/4” square headed key
(Figure 11-13 ) into the square latch hole and turning the key towards the
center of the door panel. This will pivot the locking bar into the bracket.
Both square head key latches on a door must have the latch bar pivoted
away from the outer panel to enable the door to open.
To replace a square head key latch, the Huck bolts should be cut off. Re -
move the old latch and rivet or bolt the new latch into position.
Gas Pressure Door Struts
A gas pressure door strut is a cylinder shaped tube with a sliding shaft that
uses self-generated air pressure to hold access doors in an upright posi-
tion. The strut functions by drawing in air and trapping it in the air tight
cylinder as the sliding shaft is extended. Air is exhausted and pressure is
released by pushing the sliding shaft into the large cylinder. These struts
are installed individually or in pairs and are bolted into position at the top
of the door, one on either side. Gas pressure struts are not adjustable. If
one strut of a pair is defective it should be replaced.
Two gas pressure struts are required to safely hold a skirt panel open.
To prevent the panel from falling and causing personal injury when
replacing a gas pressure strut, the skirt panel must be supported by a
device other than the remaining gas pressure spring.
Gas pressure struts do not require regular maintenance. If binding does occur, apply a light oil to the
sliding shaft and to the rubber valve where the shaft slides into the cylinder.
