Inspection manhole, SA4 System - Inspection cover

What it is

SA4 is a round stainless steel floor access cover designed for service wells and technical chambers where frequent access and a more robust cover are required. It is described as weatherproof, with power-assisted opening and a shatterproof configuration.

Main technical features

The sheet specifies a 4 mm thick stainless steel cover with hydraulic pistons, sturdy hidden hinges, and an internal locking device. Opening is up to about 100°, with a self-tightening closure and oval brass cap. A replaceable and resistant perimeter gasket is included; the surface is indicated as lacquered with glass beads.

Versions & sizes

Execution models include versions without/with insulation and options with air vent, depending on configuration. The range includes nominal sizes 620 / 800 / 1000 / 1200, with special sizes on enquiry.

Benefits (and notes)

⦁    4 mm “heavy” cover supports higher robustness at the inspection point.
⦁    Assisted opening reduces operational effort.
⦁    Note: coordinate air vent (where specified) with tightness requirements and gasket maintenance.

The FF Systems range also includes dedicated fire systems and fire-rated manhole covers.
