Round Slotted Vent Grilles

From: £30

Round Slotted Vent Grilles in painted black finish.

These grilles have two functions, either as vents or as drainage grilles. They are especially useful for inserting (rebating) into wooden floors or into wall to provide combustion air for log burning stoves and larger grilles for drainage grating outside.

Look carefully during episodes of ITVs “Emmerdale” and you may catch a glimpse of our round 12″ slotted grille in the main street (item RO12)

4, 5 and 6 inch round grilles are often used as vents in conjunction with round ducting

Drilling & mesh can be added for an additional cost, prices vary from £15 – £25 for mesh, and £5 – £10 for drilling depending on diameter.

Please see table below for sizes and specifications.
