Hospitals and other health care environments have special requirements for noise reduction to help patients heal faster and staff perform efficiently. The HL Series hospital latches are designed for quiet operation utilizing the L Series chassis to add superior strength and durability. The short throw angle allows door opening with an easy push or pull action. Mount them horizontally or vertically in either direction. Optional key override adds an anti-barricade safety feature on three functions helping prevent self-harm situations by allowing the key to override a  thumbturn being held in a locked position.

Ideal for use on:    

  • Patient room doors
  • Work areas where quiet concentration is desired 
  • Busy traffic areas to reduce noise
  • Chapels or auditoriums where noise can be disturbing 
  • Office and administrative areas
