  • Patent number: 4389795
    Abstract: A novel pelting board removes the need for pins or other tack-like fasteners and allows for better drying of the pelts along edges of the board. The board's frame of non-absorbent plastic has channels along its edges, a dam to direct air to the channels, and a lattice of girders between the edges for improved airflow. Clips hook onto the lattice girders to hold the underside and tail. This pelting board allows faster drying with reduced sticking of the pelt to the board.
