I got a call this week from a facility that needed to replace existing locksets with an anti-ligature product. If you’re not familiar with anti-ligature hardware, it’s designed for use in mental health or detention facilities, to help protect patients or inmates from self-harm by minimizing the attachment points on the hardware. Anti-ligature hardware is just one part of a safe environment for facilities with special needs, along with tamper-proof plumbing, mechanical, and electrical devices, break-away shower rods and bars, impact-resistant glass and mirrors, etc.
In the facility I met with today, the existing locks are Schlage L9000 series which made the process very easy. Schlage has recently introduced the SK1 anti-ligature knob, which can be added to existing L9000 locksets with no change to the door preparation.
Here’s some additional information about the SK1:
- Quad-grip knob design is easy to operate.
- Positive stops limit rotation of thumbturn.
- 20 degree slope on knobs and roses minimizes attachment points.
- Knob/thumbturn recessed to reduce vertical gaps.
- Available in US32D satin stainless steel finish, and 630AM antimichrobial finish.
- Concealed mounting, tamper-resistant.
- Conversion trim kit available for existing installations.
- Available for most L9000 series functions.
- UL listed – 3 hours.
- ANSI/BHMA Grade 1.
You can download the catalog cut for this product here: Anti-Ligature Catalog Cut, and if you have any questions, just leave a comment and I’ll post the answers. Schlage is currently exploring an anti-ligature lever, so I’ll post about that when the details are available.
