      Clamp Size Guide

      Optitec recommends a heavy duty double clamp for moving trailers and caravans over 1500kg.   There are numerous clamps available to fit different size drawbars. 

      Finding your perfect clamp:

      Step 1.  Locate the best position on your drawbar to place the bracket; the Optimover is effective anywhere on the front drawbar where space allows. 

      Step 2.  Measure the drawbar  height.

      Step 3.  Measure the drawbar width.

      Step 4.  Use the size guide below to select your bracket.
