Installation of the rail with ratchet clasp
• Cut the tension strap to length (pipe circumference + at least 120 mm).
• Insert approx. 100 mm of the tension strap the into part 1 and 2 of the ratchet clasp (see Fig. 8.36 a).
• Bend the tension strap.
• Insert the tension strap into part 1 of the ratchet clasp (see Fig. 8.36 b).
• Tighten the tension strap.
• Insert the long end of the tension strap into the tension strap clamp and the metal spring (see Fig. 8.37). It is not neces-
sary to mount the metal spring:
– on steel pipes or
– on pipes with an outer pipe diameter < 80 mm or
– on pipes that are not subjected to significant temperature fluctuations.
• Place the tension strap around the pipe (see Fig. 8.38).
• Position the metal spring (if mounted), the ratchet clasp and the tension strap clamp:
– on a horizontal pipe, mount the tension strap clamp on the side of the pipe, if possible
– mount the metal spring (if necessary) on the opposite side of the tension strap clamp
• Insert the long end of the tension strap into part 3 of the ratchet clasp (see Fig. 8.39).
• Tighten the tension strap.
• Cut off the protruding tension strap (see Fig. 8.39).
• Tighten the screw of the ratchet clasp.
