SAS 150 offers a secure, easy to maintain ceiling with convenient, hinge down access to the ceiling void. Ceiling tiles pivot and slide within the grid, minimising damage risk during maintenance as they hang out of harm’s way. Ideally suited to areas requiring frequent maintenance, or zones with high footfall. Potential security risks can be avoided using a simple clip to permanently restrict void access after installation.
