Vent Upgrade for Trade Dome Kerbs

Ventilation upgrade for the roof domes with the trade kerbs, simply pick your dome with kerb first then add this to the order as well and two hit and miss trickle vents will be added to the manufacture specs of the dome. Please note this can only be ordered at the time of placing the order for the dome (cannot be ordered afterwards for installation), if ordered separately or with a dome without the kerb they will be supplied separately.
