Fits Premier Patio Doors This anodized CRL OEM Replacement Threshold is a replacement for Premier Patio Door thresholds. The 4-3/4 inch (120.7 millimeter) wide threshold is supplied with a PVC Barrier Strip to protect against corrosion. For additional barrier strips order THBS8. We recommend using either M66GRY or 777GRY as a threshold sealant. The threshold can be shipped via UPS in small (1 or 2) quantities at the over sized package rate but for larger quantities it may be more economical to use common carrier.
