bustible housing, a filler and fastening material. The strain relief can be
mounted either directly on the wall, on profile rails, on vertical ladder
rungs and vertical ladder rails. Depending on the type of strain relief,
the filling material can consist of mineral fibre plates/mineral wool, PY-
ROPLUG

Block foam blocks and/or PYROSIT

NG fire protection foam.
The fastening material contained in the scope of delivery, consisting of
threaded rods, slide nuts, nuts and washers, is suitable for any possible
housing mounting.
The housing can be fastened at different points, depending on the type of
strain relief and type and scope of the cable installation.
