The 852-S72 Ligature Resistant SRLace™ was developed by Weizel Security in response to the challenge of patient usage of safe, adequate and economical footwear within the behavioral healthcare facility setting. Recognizing this issue, Weizel Security developed a ligature resistant solution. By securing the individual elastic segments to a Kevlar center bar with Kevlar thread, the individual segments cannot be removed from the center bar intact. If a segment is torn, it will only tear away as a partial segment that is far too short to be able to link in sequence to other torn segments.
