Measuring 3.5 inches wide, 0.875 inches tall, and 36 inches in length, this threshold accommodates adjustments of up to 1.3125 inches to compensate for uneven floor surfaces or out-of-square door frames. It is suited for residential and light commercial entry door applications where a consistent, adjustable seal is needed to reduce air infiltration, drafts, and moisture intrusion at the door sill. Installation is typically performed by general contractors, carpenters, or skilled trades professionals handling door and weatherization work.\u003c\/p\u003e\n\u003cp\u003eThe DAT39H is designed for use at exterior door thresholds where the floor-to-door gap is irregular or oversized.
