Inspection manhole, SA1 System - Inspection cover

What it is

SA1 is a square stainless steel floor access cover designed for service wells and technical chambers (e.g., fountain and spring wells, water interception wells, settling tanks, rainwater recovery wells). It supports inspection systems where reliable closing and maintenance handling are key.

Main technical features

The cover is described as 2 mm thick stainless steel with assisted opening, an internal locking device, hydraulic pistons, and sturdy hidden hinges. Opening is up to about 100°, with a self-tightening closure and an oval brass cap. A replaceable and resistant perimeter gasket is included; the surface is indicated as lacquered with glass beads.

Frames & versions

Frames are described as a stainless steel profile either with pre-drilled fins and dowels for direct installation on concrete or with zanches to be fixed during the concrete pour. Execution models include versions without/with insulation and options with air vent, depending on configuration.

Benefits (and notes)

⦁    Assisted opening supports frequent access.
⦁    Replaceable gasket improves lifecycle maintenance.
⦁    Note: coordinate finished level, concrete pour, and gasket tightness in the construction detail.

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