Henry Gauge PinGauge Pin, Henry Compressible, self adhesive, re-positionable (pack 12)
Designed for use with mounting bases and plates, The Henry Gauge
Pin can be placed anywhere within the footprint of the mounting base. It
compresses down to less than the thickness of a plate, without the risk of
causing any damage! Just peel away the protective liner and fix into
position on your platen. The gauge pin can then be removed and
repositioned again and again without harming the tympan sheet,
making it an all round useful little gadget!
