Eggcrate Grille

Eggcrate grilles use a square lattice core that gives a very open face, making them one of the most popular choices for extract and return-air positions in ceilings — offices, shops, kitchens and plant areas alike. Ours are made from lightweight aluminium, so they are easy to handle and fit, and versions are available with or without an integral damper. The damper option lets you balance airflow at the grille itself during commissioning, without adding a separate in-duct damper above the ceiling.

The range is split two ways. Square sizes in stock run from 100mm x 100mm to 550mm x 550mm neck (damper versions from 150mm x 150mm), ready for next-day delivery when ordered by 3pm. Custom sizes are made to order to any width and height from 100mm to 1000mm — enter your exact neck dimensions on the product page for an instant online price, with the lead time shown before you buy.

In every case the size quoted is the neck size; the overall face is 45mm larger on both axes, and each product page lists both. Wall-mounted eggcrate grilles are also available in our wall grilles range.
