Measuring Notes

Measure from the far end of the application to the point where the two walls meet at the outside corner. Note: There is no need for deducting 3” from the measurement since the outside corner piece attaches differently than the inside corner piece. The outside corner piece will extend beyond where the walls meet and clip to the end of the panels. Learn More
