Using a stud finder, locate any ceiling joists and mark their positions. It's essential to avoid these when cutting into the ceiling as it can cause structural damage. Once you have marked the joists, choose a spot that is free of obstructions for your access panel. Use the tape measure to mark the dimensions of the panel on the ceiling. Double-check these measurements to avoid mistakes before proceeding.

A main tee ceiling grid is a structural framework used to support ceiling tiles or panels in commercial and residential spaces. The system consists of long, straight metal channels known as main tees, which run in one direction and are intersected by shorter sections called cross tees. The main tees typically span the room's larger dimensions, while the cross tees create a grid pattern that provides precise alignment for the ceiling tiles. This configuration not only supports the weight of the ceiling panels but also offers space for essential utilities such as lighting, air conditioning, and fire sprinklers.
