The anodized CRL OEM Replacement Threshold stands as a versatile choice, fitting doors from a variety of manufacturers. With a width of 4-1/2" (114 mm), it includes a PVC Barrier Strip for robust corrosion protection. For additional barrier strips, THBS8 is available for separate ordering. For an effective threshold sealant, potential users are encouraged to consider options like M66GRY or 777GRY. When it comes to shipping, smaller quantities (1 or 2) of this threshold can be conveniently dispatched via UPS at the oversized package rate. However, for larger quantities, utilizing a common carrier may provide a more economical solution. This replacement threshold offers a reliable and adaptable option for those with specific door requirements.
