Click vs Hook Ceiling Grid
Click ceiling grid systems are designed for rapid installation and positive locking, making them ideal for projects where speed and straightforward fitting are important.
Hook ceiling grid systems provide a more traditional connection style and are often preferred on projects where installers want a familiar layout method.
Whichever system you choose, all parts must match. Do not mix Click and Hook cross tees in the same ceiling.
Installing a Rockfon CMC Ceiling Grid
Installing a Rockfon CMC ceiling grid system is a straightforward process when using the correct components. Main tees are installed first, followed by 1200mm and 600mm cross tees to form the grid layout before ceiling tiles are fitted into place.
For a full step-by-step guide, read our suspended ceiling installation guide, or use our ceiling grid calculator to ensure accurate quantities before starting your project.
T15 vs T24 Ceiling Grid
T15 ceiling grid has a narrower, more refined visible face and is often selected where a cleaner, more minimal finish is required.
T24 ceiling grid is the most common standard suspended ceiling grid profile, widely used across commercial installations for its versatility and easy compatibility.
To avoid fitting issues, always match the grid type to the ceiling tile edge detail:
- T15: Board Edge and Microlook Tiles
- T24: Board Edge and Reveal Style Tiles
