THE COMPLIANCE GAP
An Unmet Need in Ligature Risk
Facilities have been cited by The Joint Commission for external rings on bed restraint systems that create ligature points, which is a critical safety gap with no purpose-built solution. Until now.
THE PROBLEM
Prior to the ERSO Restraint Anchor, there was no hardware solution that could safely anchor a patient restraint system while mitigating the external ligature point.
Facilities were left choosing between patient safety and regulatory compliance.
Source: Joint Commission ligature risk standards for behavioral health & correctional environments
THE SOLUTION
Engineered to Close the Gap
The ERSO Restraint Anchor was developed directly in response to this unmet need, and shaped through beta-testing with Behavioral Health Associates, nursing staff, and facility administrators.
✓ Flush-mounts to furniture, floors, or walls - Retracts when not in use, mitigating ligature risk
✓ Restraint anchor placement - amount and placement of anchors on bed, furniture, etc., can be customized to meet customer/facility needs
✓ Spring-loaded mechanism - for restraint use, locks flush when not needed
✓ Designed for new construction - retrofit concrete floors, wood floors, masonry, and drywall
✓ Superior infectious disease control - engineered to prevent patient clogging of unit openings
✓ Visually unobtrusive — designed to disappear into the aesthetics of therapeutic environments
HOW IT WORKS
Three States. One Intelligent System.
Flush & Locked
01
When restraint is not required, the anchor sits flush with the furniture surface, floor, or wall. No exposed hardware. No ligature point.
Activated on Demand
02
Authorized staff deploy the spring-loaded mechanism when a restraint anchor is clinically needed. The anchor rises smoothly to its operational position for restraint attachment.
Reset & Secured
03
After use, the anchor returns flush and is locked down. The environment returns to a fully ligature resistant state, immediately.
WHERE ITS USED
Anti-Ligature Hardware for Every Facility Type
The ERSO Restraint Anchor is engineered for installation across the full spectrum of behavioral health, correctional, and hospital environments. Suitable for new build and retrofit.
Behavioral Health
Psychiatric & Mental Health Facilities
For inpatient behavioral health units, psychiatric wards, and mental health facilities requiring Joint Commission-compliant ligature resistant hardware integrated into existing or new furniture and flooring.
New Construction
Architects & Design
Teams
Designed to integrate cleanly into new construction, set to finished floor height and poured in, or mounted flush in wall systems. Ideal for architects specializing in behavioral health design.
Correctional
Correctional & Detention Facilities
Engineered for prison, jail, and detention environments. Compatible with correctional furniture manufacturers including Cortech and Norix. ERSO is not affiliated with the above manufacturers. Compatibility references apply to retrofit and OEM Installation scenarios.
Retrofit
Retrofit & Existing Facilities
Core-drill into existing concrete floors, anchor to wood framing, or bolt into masonry, the ERSO Anchor installs into virtually any existing structure without major renovation.
Healthcare
Hospital Safety & Patient Care Units
For hospital engineering directors and safety teams managing ligature risk assessments. Provides compliant restraint anchor points in psychiatric emergency and patient safety units.
Furniture Integration
Anti-Ligature Bed & Furniture Add-On
Retrofit directly into existing psychiatric beds and furniture during manufacture or in the field. Compatible with leading behavioral health furniture brands including Norix, Pineapple, and AHF. ERSO is not affiliated with the above manufacturers. Compatibility references apply to retrofit and OEM Installation scenarios.

COMPLIANCE & STANDARDS
Designed Around The Joint Commission Standards
Every feature of the ERSO Restraint Anchor was engineered with regulatory compliance at its core. Closing the specific gap that has resulted in Joint Commission citations.
Mitigates Ligature Risk
Eliminates the external ring/anchor point that triggers citations in behavioral health surveys. Compliant when flush-locked.
Infection Control
Designed with superior infectious disease control in mind — surface gaps minimized, openings engineered to prevent patient tampering and contamination buildup.
Patient Safety Standards
Shaped through direct feedback with Behavioral Health Associates and nursing staff. Meets the functional requirements of clinical restraint protocols.
Independent Third-Party Testing
A full end-to-end review was conducted by an independent evaluator — not just manufacturer self-certification.
Multiple additional patents pending. The ERSO Restraint Anchor is the only purpose-built, patented hardware solution addressing the ligature risk compliance gap in restraint anchor systems.
Frequently Asked Questions
Still have questions about anti-ligature hardware or how the ERSO Restraint Anchor works in your facility?
Browse the FAQs or reach out to our team directly.
-
Anti-ligature hardware refers to fixtures, fittings, and anchoring systems specifically designed to eliminate or reduce ligature points, which are areas where a cord, rope, or other material could be attached and used for self-harm. In behavioral health and correctional facilities, anti-ligature hardware must meet specific standards to pass Joint Commission inspections and maintain patient safety compliance.
-
A ligature point is any fixture, fitting, or surface feature that could be used to attach a ligature, including exposed anchor rings, door hinges, curtain rails, or restraint hardware left in a raised position. The Joint Commission conducts ligature risk assessments in behavioral health facilities, and facilities can be cited for any identified ligature points, including those on restraint systems.
-
When not in use, the ERSO Restraint Anchor locks flush to the furniture, wall, or floor leaving no exposed ring, hook, or point. This means there is no surface feature that can function as a ligature point. When restraint is clinically required, authorized staff deploy the spring-loaded ERSO anchor using a specialized key.
-
Yes. The ERSO Restraint Anchor is designed for both retrofit and new construction installation. It can be retrofit directly into existing psychiatric beds and furniture, including products from manufacturers like Norix, Cortech, and Pineapple Furniture. It can also be drilled into existing concrete floors, bolted into wood framing, or anchored into masonry walls.
-
The anchor is designed for any facility that requires a compliant patient restraint point in a ligature-resistant environment. This includes inpatient behavioral health and psychiatric units, juvenile and adult correctional facilities, hospital psychiatric emergency departments, and secure residential treatment facilities.
-
Yes. In addition to internal development and beta testing with Behavioral Health Associates, Nursing staff, Administrators and Facilities personal the ERSO Restraint Anchor underwent a full end-to-end independent third-party evaluation. It also holds three granted US patents with additional patents pending.
-
The Joint Commission requires behavioral health facilities to conduct ligature risk assessments and remediate any identified ligature points in areas where patients may be unsupervised. This includes ensuring that patient restraint anchor systems do not present an exposed ring or fixture when not in active use. Facilities that fail to address these points risk citation during accreditation surveys. The ERSO Restraint Anchor was specifically engineered to close this compliance gap. ERSO is not affiliated with the above manufacturers. Compatibility references apply to retrofit and OEM Installation scenarios.
