About our Bowers XT Bore Gauge Extensions
Bowers XT Bore gauge extensions allow you to screw the Display Unit in one end and Head Unit at the other to increase the measuring depth of your gauge.
Extensions are interchangeable between the XT models e.g. XTA, XTD and XTH. Their only restriction is the head diameter range (e.g. a 6mm-10mm extension will not fit a 10mm-12.5mm head etc.). Please check your XT gauge head matches the size range of head above.
