Both the H-1 and H-1L Stake Holders have an 8 mm square hole that will accommodate any Fretz miniature stake with an 8 mm square tapered shank. The H-1L extends the position of stakes farther from the edge of your work surface for greater flexibility. Both stake holders can be mounted either directly to your bench top using the included hardware or secured to the VB-1 Block, which can be secured in a vise for stability. The VB-1 Block is made of solid cherry wood, with pre-drilled holes for mounting either stake holder.
