Brett Martin 450 x 350mm Chamber Reducer B6350

Brett Martin Inspection Chamber Reducer - 450mm to 350mm (B6350)

A polypropylene reducing ring that restricts the opening of a 450mm inspection chamber to 350mm. Clips snap the ring into position and moulded screw holes allow a permanent fixing, and it fits both square and round frames.

Restricting the opening is standard practice on deeper chambers to prevent person entry. Used for 450mm chamber installations with inverts beyond 1.2m and for deep chamber runs where a restricted access opening is required.
