All Precision Roof Hatches are fabricated of heavy gauge
steel or aluminum properly finished to withstand rough handling and exposure
to the elements. Insulation in the cover and curb minimizes the effects on
the building's HVAC system. A rubber gasket, in its own formed track,
tightly seals the lid against the curb, making the unit weathertight. The
cover is devoid of all hardware except for the handle, negating areas where
corrosion and rust can form. All hatches are provided with padlock
provisions both internally and externally.
The PLH hatch series provides the most economical means of
accessing the roof from the building's interior when used with a Precision
FL series ladder. The safety of the climber and ease of operation of the
hatch were given attention in designing the PLH. A zinc plated cablock with
a built-in inside handle is provided. Support arms found on some competitive
hatches are not needed, therefore the space normally required by the arm is
available to the climber.
The PSRH hatch series were engineered to be compatible with
the Super Simplex Disappearing Stairway and the Precision Ships Ladder, as
well as other "steep" ladders. As with other Precision products, each unit
is tested in the plant to assure smooth opening and closing with one hand.
These units are also provided with a 1 point cablock.
Metal-pan and poured-in-place concrete stairs have not been ignored by
Precision. When this type of access is used, the PNRH
series hatches should be used. The Super Simplex units that that require a
roof deck opening of 5' 4" or longer would also use this model. Additional
pressure intensifiers compensate for larger, heavier covers allowing the
operation to be as easy as with a ladder hatch. Security is provided by a
2-point slam-lock.
