• Fowler/Bowers 54-336-307 XT Extension

    Technical Specifications:

    • Length: 40"/1000mm
    • Diameter: 1.365"
    • Only compatible with XT Heads from: 1.375"/35mm and larger

    Note: The XT Extension 54-336-307 is not compatible with the XTA Analog Holemikes. If operators need to use a 40" extension to get down to take a bore measurement, the XTH Pistol Grip or the XTD Electronic Holemike will have to be used.

    The Fowler/Bowers XT extensions can be used with the XTH pistol grip readouts, XTD electronic holemike readouts as well as the XTA analog holemikes. The maximum depth recommended for the XT bore gages is 2 meters. If users are measuring bores at depths of 12" and greater, we recommend speaking with one of our inside sales reps in regards to using measuring heads with spherical anvils.
