  • 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

  • Meets the requirements of CD 534 v0.1.0 (formerly HA 104/09).

    CD534 v0.1.0

  • Indexed corners ensure correct orientation first time, every time.

    Indexed corners

  • 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.

  • Non rocking 3-point suspension design, for silent operation.

    3 point suspension

  • 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.

    Gussets icon

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

    Mortar Apertures icon

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

    Rounded frame flange

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

    Keyway lifting point in the frame

  • Mechanical lifting points are provided.

Specifying Products under BS EN 124

The BS EN 124 standard serves as a general guide for determining the stability of products, and it outlines the parameters for different classes of products in terms of static load tests. However, it doesn't offer much specific information about the dynamic loads that various traffic conditions on modern road systems can impose.
