We are 100% willing to work with you to get the fit right. Let's say you brought a house and it already comes with a peg board in the garage and you aren't sure where it came from? We can send you sample pegs to try out before your order is created. Another great aspect of everything we sell is that the pegs on the back screw on and off. Decide to move an item to a completely different peg board with a different sized hole? Screw off the old peg and screw on the new one. It's that easy.
