SafetyJacs are manufactured with innovative patented technology that produces the cut to length jacketing with extremely low tolerances of +/- 0.0001″. The leading edge incorporates a ½” folded hem, while also having all circumferential edges deburred. SafetyJacs have been designed with both Safety & Profitability in mind for all users. With the ½” hem and factory deburred edges, this greatly reduces the potential of cuts and lacerations when handling. The ½” hem on the longitudinal edge also provides more rigidity reducing the amount of workmanship required to install when a “fish mouthing” effect often occurs on various types of insulation, thus increasing Productivity and Profitability.
