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.
