Creating a stiff and gapless connection between board halves, the crossbar and lever rotate out of the way leaving nothing hanging over the edges while touring or splitting. Clamping tension is easily fine tuned by turning a set screw. The Spark Crossbar Clips are made from aluminum and brass in as elegant low profile design of two moving parts. As a bonus feature, they can be entirely set up with the M3 hex bit on your spark tool. The Crosssbar clips have been redesigned for 18/19 to perfect the features of this product. The same general principle, but refined and re-mixed for a better connection with vast adjustment.
