This is a professional Tecomec  5" diameter (130mm) commercial quality Italian designed Tap-N-Go trimmer head. This Tap-N-Go line advance head has an Aluminum bump knob for extended wear resistance. This is a simple reliable head with a high-tech wind-in-the-head design for easy line reloads. The head has long lasting brass eyelets that help prevent trimmer line breakage. The head is shipped with 13' of .105 trimmer line, however you can use trimmer line sizes .095", .105" and .118" sizes in all shapes.  The size of the arbor adapter bolt included with this head is 10mm x 1.00 LHF. 


Note: The shaft bolt is shipped separately but the shaft bolt is very easy to install, simply squeeze the two tabs on the trimmer head body and the head comes apart, drop the shaft bolt in and then squeeze the head back together. We also stock all the parts for this trimmer head.
