The enlarged frame corners help to dissipate loads onto the foundation, providing a longer service life and increased reliability.

Safety keyway prevents accidental disengagement of the lifting key during the handling process.

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

Indexed corners ensure correct orientation first time, every time.

Surface texturing above and below the flange enables better mortar engagement, reducing any lateral movement which could result in cracking.

The covers feature a universal beam (also known as an I beam) providing significant improvements to rigidity, reducing seat wear for an enhanced service life.

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.

Keyway lifting points are provided on the frame for safe handling.

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.
