Eggcrate Grille
Eggcrate grilles for wall-mounted extract ventilation — the square-cell grille with the highest free area of any standard grille type, letting air pass with minimal resistance and noise. Available in stocked square sizes from 100mm to 550mm, with-damper versions for balancing, and custom sizes made to your exact dimensions.
The default extract grille
The open eggcrate core hides the duct behind it while presenting a clean, unobtrusive face, and its low pressure drop makes it kind to extract fans. Use it on extract points in offices, commercial interiors, kitchens and washrooms — and on transfer openings between rooms, where its two-way appearance works from both sides.
Stocked, dampered and custom options
- Square sizes in stock — plain eggcrate from 100mm to 550mm square, and eggcrate with an integral damper from 150mm to 550mm, all listed with face sizes (neck plus 45mm each way).
- Custom sizes made to order — plain or with damper, manufactured to your width and height with the price calculated instantly on the product page.
The damper versions let each extract point be balanced at the grille during commissioning — useful when several grilles share one fan and the nearest would otherwise take more than its share. Face sizes are quoted on every listing alongside the neck, so openings can be planned exactly. Pair any size with a grille box to connect round ductwork to the rectangular neck. Stocked squares ordered by 3pm are despatched for next-day delivery, with free UK mainland delivery over £400 ex VAT.
