Applications • L4 +
In addition to the outdoor capabilities of the L4, the L4+ has been designed to
perform many additional functions for interior work:
The W1 wall and vertical mount, provided in the
system, allow the L4 + to be attached to T-bar
wall angle. A "0" height mark on the W1 sets
the beam at finished ceiling elevation for
installing wall angle. A -2" (-50mm) mark sets
the beam at the center of the system magnetic
targets for installing the grid.
The W1 mount, makes vertical setups for steel
wall alignment easy. Setting the W1 mount to
the "vert" mark aligns the rotating beam with
the edge of the mount to align top, bottom
channels. The mount can then be moved to a
2" (50mm) offset to allow the magnetic targets
to be used for checking stud placement.
With its 90º fixed spot, the L4 + eliminates the
need to use 3-4-5 calculations or other difficult
methods to align right-angle intersections. One
person can easily accomplish layout tasks,
even on large commercial sites.
Transferring points from floor to ceiling or
maintaining alignment on high-rise structures
can be accomplished very accurately with the
L4 + . The low cost accessory P1 plumb plate is
used to precisely locate the L4 + over a point for
this type of work.
