Shear Power
A mechanical device used for affixing paper sheets to display boards but which facilitates their easy removal. It has a pointed central metal shaft to pierce the paper and penetrate the display board surface. The paper is held as the shear in the shaft balances the weight of the paper. A green or brown 3/8" dia round metal head on the shaft holds the paper against the board. The devices come (40) to a card and we'll send you (4) cards per order.
