      from 100mm to 3 meters, for horizontal or vertical mounting.

v      The units are built as freestanding or bolt-on modules, complete with leveling braces and bolting down holes. They are designed to suit existing machine and site conditions.

v      The framework is rectangular hollow section with specialized corner bracing incorporating the fine adjustment mechanism and mounting for the Turner Bars.

v      In order to avoid material stress turning bars can be supplied with an optional air connection which puts a protective air cushion between the turning bar and the web.
