In addition to ensuring equipment returns to its proper place, this caster replacement system promotes fire safety in your kitchen. For your kitchen's fire suppression system to work properly, all of the equipment under it needs to be aligned in the correct location. This set easily marks out where each piece of caster-mounted equipment goes so that it can be returned to the right spot, and it also helps to lock the equipment in place for added safety, reducing the risk of displacement and fire hazards. It complies with NFPA codes 17A (5.6.4) and 96 (12.1.2.3).
