Woody's introduces a new Double Digger Aluminum Support Plate. These plates feature a dual stud mounting configuration that will give more stud rigidity with less weight than steel plate or two single aluminum plates. They are available for use with 5/16" and 7mm Traction Master Push-Thru Studs. The mounting holes are spaced the same as Bender Stud Mate plates. The dome of the Double Digger has been increased to take complete advantage of Woody's patented dished head design on their famous Traction Master series studs. 5/16" or 7mm. * 7mm
