Here are the updates of this newly re-designed product:
Increased clamp travel and leverage: The lever now flips 180 degrees versus 90 degrees, which allows it to open more making it easier to slide the board halves together. Improved leverage makes it easier to clamp shut.
Better durability: The crossbar now slides under a brass shear bushing rather than the aluminum L bracket, which eliminates aluminum on aluminum wear.
One less screw: The lever now pivots on a mounting screw instead of an additional screw on the crossbar.
Increased adjustability: 50% more range than the 17/18 version.
More connection: U-shaped cutouts in the crossbar surround the mounting hardware for a more solid connection.
Still lightweight: Technically, this new design is 7 grams more per clip. (48g per clip with screws)
