Review on 🔒 Revolutionary Pack Hole Locking Plugs Panels for Industrial Hardware: Enhancing Efficiency and Security by Jason Hayes

These dowels fit perfectly into the 1" diameter hole in the top boards of our Silverton (from Sam's Club) pergola. These ten boards have fifty deep holes (1 inch in diameter) at the top where the bolts are screwed into the cross. Boards. This leaves any holes open to be filled with rain/snow etc. Poor pergola design. . . but they were perfect for plugging all 50 holes.
