LR-SDS
Ligature Resistant Sliding Door System
The patented LR-SDS Ligature Resistant Sliding Door System is designed for behavioral health environments, seamlessly integrating into a standard 1-3/4″ thick door to eliminate accessible ligature points at the top of the door and within the track. The flexible system can be mounted to a contractor-supplied header or the Accurate Fast Frame for surface-mounted applications, with specialized functions including electronic latch retraction for medical gas enclosures. A minimal 1/8″ gap between the door and wall and a two-piece floor guide with quick-release capability support enhanced safety and anti-barricade efforts. By latching vertically into the track with a concealed rod, the LR-SDS can also reclaim up to 30 square feet of space compared to a traditional swinging door.
- The concealed track system suspends a 1-3/4" thick door while maintaining a minimal surface-applied profile, with no exposed track anchor points or accessible cavities.
- A concealed floor guide maintains door alignment and keeps the door positioned close to the wall throughout operation.
- A concealed vertical locking bolt engages into the track assembly, providing privacy and security without an exposed latch bolt or conventional strike at the door edge.
- The top edge of the door and operating components are concealed within the track assembly, reducing accessible ligature points and opportunities to manipulate the top of the door.
- A variety of specialty mortise lock functions are available and can be furnished with the applicable ligature-resistant hardware including ligature resistant thumb turn, handles and indicator options.
- Select lock functions incorporate an override feature, allowing authorized staff to gain access from the exterior in an emergency.
- An optional anti-barricade floor guide allows staff to quickly swing the door away from the wall enough to restore sliding operation in a barricade situation.
- In addition to locking in the closed position, the system can be configured with additional locking positions, including the ability to secure the door in the open position when required.
- Because the door slides parallel to the wall rather than swinging into the room, the LR-SDS eliminates the traditional door swing area, allowing more efficient use of patient-room space.
- Impact tested using a pendulum methodology consistent with Section 6.1.1.2 of ANSI A250.13-2014. At an impact energy of 150 ft-lb, the system remained operational, including after damage/failure of the test door panel.
- The LR-SDS is available with an optional Ligature-Resistant Shoe that captures the lower leading edge of the door when closed and provides additional resistance to lateral forces resulting from patient abuse.
- The track assembly utilizes two ball-bearing carrier blocks, each rated for a dynamic load capacity of 1,240 lb.
- The self-latching configuration was smoke tested in accordance with ANSI/UL 1784-2015 using a silicone bulb seal. The tested assembly demonstrated an air leakage rate of 0.92 cubic feet per minute per square foot of door opening, compared with the test criterion of 3.0 cubic feet per minute per square foot of door opening.
