Vent Units for Doors

  • Available in standard sizes to suit door thicknesses from 35mm to 56mm.
  • Available in a white or brown finish.
  • Also works in conjunction with extractors.

The vents are available in two standard sizes but as always, other sizes and colours can be made to suit clients’ needs. Furthermore, available in standard white finish or brown.

Application Instructions

The vent grilles are simple to install. Three vents are required across the bottom of the door. Simply cut three holes to suit the vent diameter. Each grille comes in two parts which are then pushed together through the prepared hole with no need for any further fixings.

Standard sized grilles are made to suit door thicknesses from 35mm to 56mm but can also be made to suit thinner doors from 28mm to 45mm.
