Attachment Methods

• The GMK-RC roof clips are used to secure IceStop
heating cable. The clip attaches with adhesive (not
supplied by Thermal Management) to many types
of roofs and gutters.
• Several adhesives are recommended by Thermal
Management. See Table 3 on page 11 of this
manual or contact Thermal Management for
alternatives.
• On a standing seam roof, use four clips on each
seam being traced. On a flat surface, use one clip
for every 5 to 10 feet (1.5 to 3 m) of unsupported
heating cable and at every change of direction.
• Follow all recommendations from the adhesive
manufacturer with regard to cleaning and prepar-
ing the roof surface for the adhesive.
• After determining the heating cable layout, fasten
the clips to the roof with the adhesive and allow
the adhesive to cure before installing the heating
cable.
• Thread the heating cable through the clips. Use
additional clips wherever the heating cable may be
subject to abrasion from movement.
Important: How well the adhesive holds can be
strongly affected by how well the surface to which it
will adhere is prepared and by what type of adhesive
is used. Be sure to follow the recommendations of the
adhesive manufacturer.
