Anchoring heating cable to foundation base
For applications where the mat or detached cable must be anchored to a solid foundation base such as asphalt
coating or concrete stairs, use galvanized steel strapping (available as an option, sold separately).
• Strapping must be installed perpendicular to the cable.
• For OWS-T mats, install two rows of strapping 18” (457 mm) apart for models OWS-T-24 and 30” (762 mm)
apart for models OWS-T-36.
• For detached cable, maintain a minimum space of 36” (914 mm) to 48” (1219 mm) between strapping.
• Firmly anchor strapping to the foundation base using concrete anchors or nails.
• Attach the cable to the strapping (see figure 7). Do not fasten cables too tightly to avoid any damage.
Cable should have some slack.
