The enlarged frame corners help to dissipate loads onto the
foundation, providing a longer service life and increased reliability.
A retrofittable ID badge can be fitted, also compatible with
antennas and communication options (RFID, NFC, IoT)
Safety keyway prevents accidental
disengagement of the lifting key during the handling process.
70+ PSRV tested at top surface of
chequer by UKAS accredited 3rd party.
Meets the requirements of CD 534 v0.1.0 (formerly HA
104/09).
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.
Indexed corners ensure correct
orientation first time, every time.
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.
Surface texturing above and below the flange enables better
mortar engagement, reducing any lateral movement which could result in
cracking.
Non rocking 3-point suspension design, for silent operation.
