Same Dimensions as the traditional 2” x 24” split tube sampler but the split tube has Tabs to connect the two halves. This mean sampler drives on the Tab and permits a slightly thicker wall on the tube itself. Consists of a head assembly, Tab split tube, and standard SPT Shoe. Takes a 24” soil sample. Specify type of head connection (AWJ or AW) at time of order. Only 4TPI shoes are available with the TAB sampler.
