What is holeboard?

As an AI language model, I do not have sufficient context to understand what you are referring to as the holeboard.

However, if you are referring to the term "pegboard" that might be commonly used to describe an item with holes, here is some information about it:

A pegboard is a board with multiple holes in it, into which specially designed pegs can be inserted. Pegboards are often used for organizing and storing tools, as pegs can be moved around to accommodate different items. They can also be used for crafts and DIY projects. Pegboards are typically made from materials such as wood, plastic, or metal. They are often hung on a wall with hooks or other hardware. Pegboards are generally easy to install and provide a flexible storage solution for a variety of items.
