The T-Bar Extension adds an extra 3 feet of rail in the middle of the 8 foot Flat BAR, making a total grinding length of 11 feet. It comes with an extra Pivot Foot in the middle for stability, so you can lock in at speed and go the distance. Not long enough? Add as many as you’d like and grind for miles. The T-Bar Extension is the item in RED displayed in the picture above. *This extension works with the Flat B.A.R. and does not include a Flat Bar.
