•Natural
Compliances:
Compliances as noted on each page of the catalogue include:
• CSA Certified
• UL Listed
Old Way
Conduit running in a cement slab is bent
90º to run through a hole drilled in the form.
Drilling takes time and damages the form.
Stripping form often damages conduit stubs.
Varying length of stubs requires individual
measuring and cutting of conduit drops.
Red Dot Way
Conduit running in a cement slab is attached
to a 90º concrete slab insert, or conduit is
bent 90º and is threaded to a straight insert.
Nail or screw fitting to wood or metal forms.
After concrete is poured and forms stripped,
conduit drops quickly into fittings. Drops are
easily measured from ceiling line to switch or
outlet height and cut in uniform lengths.
