Product Description
Series NV grilles allow air to transfer between adjacent areas whilst remaining vision proof.
They are suitable for mounting in doors, partitions and walls and are supplied with rear telescopic frames for matching front and rear borders.
With minor modifications these units will prevent light transfer and in this mode are ideally suitable for ‘dark room’ applications.

Frames are mitred with mechanically jointed corners and the blades are set in cores at 20mm centres.
Blade cores can be supplied without frames.

Standard Fixing
Frames supplied with pre-punched holes in front face, unless otherwise requested.
