What you can change:

• Hole size: 5 mm, 1/4 inch (6.35 mm), or a custom diameter.

• How much smaller the pin is than the hole, and how far it reaches into the cabinet side.

• Shape: L bracket, flat spoon, or a sleeve with a bore.

• How far the rest projects, how wide it is, and how thick it is under the shelf.

• An anti-tip lip, and how tall and thick that lip is.

• For a sleeve, the bore diameter. Zero is a solid pin.

Load: these pins are for light cabinet shelves, four pins under one shelf. A 5 mm plastic pin is a small section. Do not set books, appliances, or anything you would mind falling on a shelf held by these pins. The cone at the root of the pin has to sit against the cabinet face, not inside the hole. If a pin is loose, do not use it.
