You get what you pay for
Color: 48‘’ Metal Hooks
You should stagger each rail when installing. If you put them in a straight line there’s not enough space to properly use all of the hooks.

Outstanding quality, smart design, and built for real use
Color: 48‘’ Metal Hooks, Color: 48‘’ Metal Hooks
It’s sturdy, well-made, and thoroughly designed. I was so impressed that I decided to get another one and gifted it to a friend, and they love it. The metal rails are thick and solid, and the adjustable hooks are heavy duty with a protective coating that prevents scratches of tools. Everything feels durable and secure. No bending or wobbling, even when loaded with shovels, brakes, brooms, ladders, and other garden tools. The 440 pound capacity is no exaggeration. Installation is pretty straightforward and the flexibility to position. The hooks makes it easy to customize for different tool sizes.

An incredibly easy to use shelf pin hole jig

A solidly constructed jig used for easily creating either a 5mm or 1/4" shelf pin holes. Mark your control line and place the jig on it while using two thumb screws that act as both a clamp and edge guide for perfectly aligned holes. Various thumb screw holes allows for holes that are closer to the edge of your work or for holes further in from the edge.

Good product
Size: 11 Holes
Works well for the must part. I ended up buying a different style bit collar stop because the one provided wasn't solid enough for me. Might be a personal preference

Awesome tool
Very easy to use, only issue I had was the location pin was a bit tight. Chucked it in the drill and polished it up with a scotch-brite and it worked perfectly. The end to end symmetry made it easy to move from one side to the other. Good price as well!
