The PT-RGCH hanger brackets are suitable for use with Pr?tecTHERM heating cables, to help protect the cable from getting damaged over sharp edges as it enters a downspout or goes over a gutter. Use hardware and follow instructions recommended in this guide. The use of any other hardware or technique should be avoided as they risk damaging the heating cable and cause a risk of fire, a risk of electrical hazard or the heating cable’s poor performance.
