Feeling the up-down grind? Much like the T-Bar Extension, the A-Frame fits in the middle of the 8 foot Flat B.A.R., utilizing the ability of the Pivot Feet on the Flat B.A.R. to stay flat while the rail angles up toward the center, then back down again on the other side. The A-Frame is adjustable from 13.5” to 18.5.” With a center Pivot Foot for added stability, this option will up the ante on any trick. You can also hit the rail on the down-slope to practice for handrails. The A-Frame Extension is the item in red in the picture above. *The A-Frame Extension works with the 8 foot flat B.A.R. you must purchase separately.
