Anti-Ligature HVAC Covers: Safety-Engineered for Behavioral Health and Correctional Facilities
Precision-Fabricated. Tamper-Resistant. Built to Perform in the Environments That Demand the Most.
Arsco Custom Metals designs and manufactures anti-ligature HVAC covers engineered for the rigorous safety demands of behavioral health facilities, psychiatric units, mental health centers, correctional institutions, emergency departments, and other high-risk institutional environments. Every enclosure is custom-made to order in the USA, built to eliminate ligature points, resist tampering, and preserve full HVAC system performance without compromise.
Why Anti-Ligature HVAC Covers Are Essential
Standard HVAC units introduce serious hazards into behavioral health and correctional environments. Exposed brackets, accessible end caps, protruding hardware, and conventional ventilation grilles all create ligature points that represent an unacceptable risk to patient and occupant safety in closely monitored settings.
Anti-ligature enclosures directly address this by replacing standard HVAC covers with purpose-engineered enclosures that eliminate every accessible anchor point while preserving the airflow and mechanical performance of the underlying system. Every design decision is deliberate: sloping tops prevent anchoring, recessed tamper-resistant fasteners eliminate grab points, and fully welded construction removes the gaps and edges that make standard products dangerous in these environments.
Behavioral health facilities, correctional institutions, and emergency departments are subject to strict compliance requirements from accreditation bodies, (add comma) including the Joint Commission, which evaluates ligature resistance across the full environment of care. Specifying anti-ligature enclosures for HVAC systems is an essential step in closing the compliance gaps that standard equipment leaves open and in demonstrating a facility-wide commitment to patient safety.
Arsco Anti-Ligature HVAC Cover Features and Configurations
Arsco Custom Metals manufactures anti-ligature HVAC covers in heavy-gauge stainless steel and steel with a (added a “a”) durable powder coat finish, engineered to meet commercial-grade standards for durability, cleanability, and long-term performance in high-traffic institutional settings. Our enclosures are designed to house fan coil units, heat pumps, PTAC units, induction units, and radiant heat systems.
Wall-Mounted and Floor-Mounted Configurations
Arsco anti-ligature enclosures are available in both wall-mounted and floor-mounted configurations to accommodate the full range of HVAC system types. Sloped top wall-mounted and flat top wall-mounted options are available, as are sloped top floor-mounted and flat top floor-mounted configurations. Sloped top configurations are specified most frequently in higher-acuity patient environments where eliminating every potential anchor point is non-negotiable.
Airflow, Access, and Performance
Anti-ligature air conditioning guards are engineered to preserve optimal airflow while enclosing HVAC units behind a fully ligature-safe enclosure. Ventilation grilles are fabricated with ligature-resistant geometry, maintaining system performance without introducing the anchor points that standard grille designs create. Maintenance access is retained through tamper-resistant access panels, so authorized technicians can service equipment without compromising the safety integrity of the enclosure.
Custom Dimensions and Finish Options
Arsco Custom Metals routinely customizes anti-ligature HVAC cover dimensions, cutouts, and attachment methods to fit exact project-specific field conditions, for both new construction and retrofit applications across behavioral health, correctional, and institutional environments. These are available with a zinc-rich primer undercoat finished with a smooth, low gloss, anti-microbial white powder coat, supporting the aesthetically pleasing, therapeutic environments that behavioral healthcare (Only spot that uses “behavioral healthcare” and not “behavioral health”) design increasingly prioritizes.
Key Features & Benefits
• Patient Protection
Designed to safeguard tenants and patients by eliminating tampering and ligature risks.
• Enhanced Durability
Extends the lifespan of HVAC control systems by providing robust protection.
• Effortless Maintenance
Allows staff to access internal components easily for cleaning or servicing without compromising security.
• Secure Staff Access
Medical unit staff can adjust temperature or other controls through the tamper-proof, locking, access door, ensuring functionality without tenant access.
Advanced Design & Construction
Our enclosures set the standard for security and durability:
• Removable, Locking Panel: Each enclosure includes a fully removable, locking panel for secure maintenance access.
• Optimized Ventilation: Designed with a perforated layout to ensure accurate air temperature sensing and effective control.
• Preserves Seal Integrity: Maintenance access is designed to retain the integrity of the pick-proof caulking.
Compliance & Durability
Our enclosures comply with New York State OMH ligature-resistant specifications, ensuring tamper resistance, restricted access, and no ligature points. Built to withstand the harshest environments, each enclosure features:
• Material: 14-gauge cold-rolled steel for superior strength.
• Finish: Powder-coated with both a zinc rich primer and a low-gloss, matte white for durability and a professional appearance.
• Maintenance Access: With the use of two keys, staff can remove the access panel to expose the top and front of the entire HVAC element, allowing for efficient filter changes and servicing. This process is completed seamlessly without disturbing the pick-proof caulking.

Industries That Specify Arsco Anti-Ligature HVAC Covers
Arsco Custom Metals ligature enclosures are specified across a wide range of institutional environments where safety is the governing design priority.
Behavioral health facilities specify anti-ligature air conditioning guards for inpatient psychiatric units, crisis stabilization units, and any patient environment where standard HVAC units present an unacceptable ligature risk. Correctional institutions require the same rigorous standards, with wall-mounted and floor-mounted enclosures built to withstand the demands of high-use, closely monitored spaces. Emergency departments and crisis centers are increasingly specifying anti-ligature solutions as behavioral health patient volumes grow and the environment of care standards are applied more broadly across acute care settings. Mental health units within general hospitals represent another area of growing demand, as facilities recognize the need for consistent ligature-resistant coverage throughout any space where at-risk patients are present.
