Notes for Use

Notes for Use

  • The beam width needs to be known in advance, as the flange width is needed to determine the location of the fixed roller.
  • The beam flange should be a consistent width, with no cutouts or notches that would allow the roller to roll off.
  • Block or clamp the end of the beam to keep the roller from rolling off using 702067-1 end stop.
  • The beam must be level, as rollers do not have a brake.
