This range of recessed covers is designed to be in-filled with a suitable
screed or concrete, and are available in a range of clear opening sizes
and feature, as standard, four locking screws and rubber neoprene seal
to resist gas egress and water ingress.
The standard tray depth is a nominal 40mm unless otherwise indicated.
Full loading capability is achieved when filled with C25 concrete. For
superior finishes, our triple-sealed aluminum products are recommended
– CALPRO40 and CALPRO80.
