Schlage offers a comprehensive portfolio of door hardware that reduces the risk of injury or death due to ligature strangulation in all areas, but the HSLR (High Security Ligature-Resistant) trim is specifically recommended for high-risk applications. The patented crescent-style handle design has quickly become the standard for ligature resistance and accessibility. It is recognized by the widely-accepted New York State Office of Mental Health (NYS-OMH) Patient Safety Standard and achieves a "paperclip protection" designation on the mortise chassis. Optional key override adds an anti-barricade safety feature on four functions helping prevent self-harm situations by allowing the key to override a  thumbturn being held in a locked position.

Ideal for use on:    

  • Any high-risk behavioral health setting
  • Hospital room doors
  • Detention center doors
