All sizes are nominal and are subject to manufacturing tolerances that may vary ±1/8″. Exact fitting may require on site adjustment by the purchaser. Exact size and other unavoidable variables such as dye lot color variances, lighting conditions, pattern matching, directional materials, expansion and contraction due to environmental conditions. Project with exacted visual requirements and expectation must be identified for our special attention prior to ordering.
