  • 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

  • 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

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

    Indexed corners

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

    Keyway lifting point in the frame

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

    Mortar Apertures icon

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

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.
