They are intended for reference, not as design specifications.

Ratchet lock Clamp Design Concept Individual closure mechanism (screw or ratchet lock) combined with perforated steel band – clamps can be round or have an irregular form. Available as kits, in bulk or to customer’s specification. Special versions are available with integral tolerance compensation and non-perforated band. Universal clamps are available in standard widths and thicknesses. The band dimensions should be chosen to give the necessary radial force (clamping force) to ensure the required retention properties under the anticipated ambient conditions. Perforated steel band Assembly Recommendations...

Assembly instructions Screw lock type Determine the clamp length, e.g. wrap around object to be clamped and add approx. 50 mm. Cut off band to required length. To avoid possible injury remove sharp edges with a file and trim corners at an angle. Insert approximately 30 mm of band material through the top of the retaining slot and fold backwards underneath the remaining strip. Position clamp over object. Insert free end of the band over the hooks and under the screw, protruding past the body of the screw lock. Engage the hooks in the perforations at the tightest possible position. Tighten the...
