It is the customer’s responsibility to make this panel work for your needs. In most cases, this panel will require some custom cuts on-site to meet your needs. This is typically done with a metal straight edge, a sharp utility knife, and a back and forth motion along the cut to break off the excess material (tools supplied by the customer).
There will be a strict no return policy so only order what you need or order an extra panel for any onsite adjustments/mistakes or future needs. Do a trial cut in a small area like a corner to get the cut and break process down before making a major cut. Instructions will be provided.
