(6) Minimum cutting length
As illustrated in Fig. 10, it is sometimes necessary to cut studs 30 mm or less from the ceiling surface when
installing fluorescent lamps in electrical installation work. The Model CL 10D2 permits cutting protruding studs to
a minimum length of 24 mm from the ceiling surface.
In addition, when installing ducts in air-conditioning equipment installation work, it may be necessary to enclose
the ducts with insulation (lagging) after installation to prevent the formation of dew. In such a case, studs must be
cut as short as possible so that they do not protrude from L-shaped angles, in order to prevent damage of the
lagging. As illustrated, the Model CL 10D2 permits cutting of studs within an L-shaped angle measuring 25 mm x
25 mm x 3 mm (t).

hanging studs is often only one of several jobs that must be performed.

Accordingly, it is sometimes necessary to put the stud cutter aside and use
both hands for some other job. In such cases, the hook is very useful for
hanging the stud cutter from a nearby conduit, steel grounding material,
cable rack, or similar support when not in use.
