The ZIPBOLT UT MINI Line Bored is the result of an engineering challenge to retain Zipbolt’s UT design and to scale down the size while retaining the strength, we did it! It is only 12.5mm or 1/2" thick in profile with all metal housing. This model allows the user to install the connector by passing the shaft through the bored edges and assembling the panels thereby only revealing the housing holes (25mm), this is in contrast to full surface machining.
