Please order material by product number, specifying length required per piece and the number of pieces. Most weatherstrips are offered in standard sizes. If it is not practical to furnish the size ordered, the next larger size will be furnished and charged.

Thresholds are maintained in standard sizes with 1/2" extra length on thresholds thru 47" and 1" extra length for thresholds 48" and longer to allow for fitting and field trim, unless exact net cut size is specified. Cut lengths under 24" will be charged as 24".

Thresholds, perimeter gaskets, astragals, and door bottoms are punched or drilled as standard, unless otherwise specified in this catalog. Material can generally be supplied without holes by stating "No Holes" on the applicable purchase order line.

Thresholds are punched with 12" centers. Thresholds over 8" in width will be punched with a double row. Thresholds are generally supplied with #10 flat head screws. Other fasteners are available on request.

Metal retainers for perimeter gaskets, door bottoms, and astragals are punched with 6" centers.
