  • Frame gussets are supports which reinforce the corners where the frame sections meet, distributing stress evenly, preventing damage to the frame or the access cover.

  • The high seating position ensures that forces are transmitted more directly downwards, meaning conversion of traffic loads into mortar-compatible compression forces.

    Cover support geometry
  • Holes in the frame flange where mortar can pass between the underside and top side, creating an interlock, providing greater strength.

  • Unlike sharp, square-edged frames, rounded edges reduce stress concentrations and minimise crack formation.
