K: As variant C, but with insulation.
The KDA lid is intended for pedestrian traffic.

Surface treatment:
Aluminum frame, seawater-resistant aluminum lid, and acid-proof steel brackets and fittings (316)

* Extruded aluminum frame.
* Aluminum floor plate lid w/gasket.
* Wall anchors throughout the perimeter of the frame.
* Hinged and with locking screw.
* Packed individually in plastic.

Can be equipped with locking devices to order.
1 M10 stainless steel internal hexagon screw is standard.

* Casting at the same time as the surface. The frame is rigid and will not normally be pressed.

We recommend protecting the hatch with plastic and tape when embedding. Leave the protection in place until the concrete has hardened. Wash off any spills from damp concrete/plaster as soon as possible as this otherwise gives etch marks that can only be removed by mechanical brushing after drying.

Equipment variant C is normally stocked. Special sizes can be supplied.
