Abstract: A hole drilling jig assembly for drilling holes in a support at a precise location includes a pair of locking pliers that include a pair of jaws and an adjustment screw. An eyebolt is coupled to the adjustment screw and a pulling line may be coupled to the eyebolt for pulling on the locking pliers. A pair of panels is each coupled to a respective one of the jaws. Each of the panels is compressed against a support when the locking pliers are closed. Each of the panels has a pair of apertures extending therethrough to facilitate holes to be drilled through the support at a precise location.
