ScrewLift™

Manhole cover levelling system

ScrewLift™ is suitable for use with nearly all of Wrekin’s D400 and E600 manhole covers and gully grates. ScrewLift™ is very straight forward to use and can be installed with any bedding mortar.

 Instructions:

  1. Insert all of the plastic brushes into the corners of the flange from the underside of the frame.
  2. Screw the levelling bolts into the brushes from the top side. 
  3. Using a spirit level or a straight edge on top of the frame, wind down the bolts to achieve the correct level to match the ground/ road surface.
  4. Lastly apply the bedding mortar to the manufacturers’ requirements.
