Please note that linear bar grilles manufactured to order may take longer than advertised due to - what we hope is - a temporary material shortage. Lead time is currently around 2-3 weeks. We apologise for any inconvenience this may cause. All other grilles and louvres are unaffected.

Adapters for NCD Circular Diffusers

Enables the installation of NCD circular diffusers into round duct. The adapters can be used as a direct connection to exposed circular duct, or they can be installed within plasterboard or suspended ceilings to enable a connection with flexible duct (adapters above the ceiling; diffusers below). The pre-drilled inner support provides the means to secure NCD round diffusers. Screws are supplied with the diffusers.
