Product Compatibility
TC-120 is ideal for ¾" mahogany and ironwood decking. If you are using 1" or 5/4" grooved decking, you should use the
Tiger Claw TC-G.
If using pre-grooved decking be sure that the groove is the correct dimension and location on the board so that it is compatible with the TC-120 fastener (see groove specs below). A TC-120 Slot Cutter can be used to create grooves in non-grooved boards.
The TC-120 is not compatible with the Tiger Claw gun.
