The NextGen Lift & Lock Roof Hatch Opener can be installed by
one person, but it is more efficiently installed with two
people. The estimated installation time is 1½ to 2 hours.
Because much of the NextGen Lift & Lock Roof Hatch
Opener is installed at various points on the roof access
ladder, a climbing helmet and climbing harness or fall
protection gear are required for the installer. Hard hats are
also required for any additional installers working under the
ladder.
The NextGen Lift & Lock Roof Hatch Opener is designed for
ladders that meet Occupational Safety and Health
Administration (OSHA) standards, which recommend that the
ladder be 18” wide and that rungs be 12” apart. The system can
be installed on nonstandard ladders, but the installation
process will be somewhat different and installation might take
longer than anticipated for standard ladders.
The ideal height for the winch handle that operates the
system is about 42” above the floor. This means that, on a
standard ladder, the winch portion of the Drive Unit should
be placed between the third and fourth ladder rungs. For a
nonstandard ladder, the installer can adjust the Drive Unit
location to the optimum height by moving the unit up or down
as needed to have the top and bottom bracket locations clear
of rungs (the top and bottom brackets are 5’ apart, so if one
bracket is clear of interference by a rung, they both should be).
The winch housing, which is part of the Drive Unit, has two
available mounting positions, at least one of which should be
clear of a rung and which should be used to attach the unit to
the ladder. It is not necessary to use both of these winch
housing mounting points.
Each NextGen unit is manufactured using dimensions
provided by the buyer; therefore, the unit should fit with only
minor adjustments. The standard NextGen unit, which includes
the Drive Unit and the Lifting Tube, has a fully assembled height
of 13’-6” (162”). In the event that the hatch is more than 15’
from the floor, the necessary Lifting Tube Extension (or
Extensions) is included.
