The Anti-Ligature Shop (ALS) offers three styles of ventilation grills: unframed, framed, and raised frame with hinge. The framed and hinged grills allow for easy access and maintenance without damaging paintwork or pick-proof caulk. The grills are available in either mild steel or stainless steel, and feature an attractive white powder coat finish. The holes are 3/32” for ligature resistance.
