Adjustable Double Bubble Under Door Seal for Exterior Doors, 32 inch Door Sweep with Drip Edge & Drainage Channel, 32 Inch White

Seal the gap beneath your exterior door—without removing the door. Our Adjustable Double Bubble Door Sweep creates a tight, reliable barrier that helps keep drafts, dust, water, and insects where they belong: outside. The two flexible “Double Bubble” fins adapt to uneven thresholds and seasonal changes, so your entry closes with a confident, consistent seal instead of a whistling gap. Engineered for fast, frustration-free installs, this exterior door sweep is adjustable to close under-door gaps from 3/8" to 7/8". A shaped drip edge and a punched drainage channel work together to redirect rainwater away from your threshold, helping keep entry rugs drier after storms or pressure washing. It’s pre-notched to clear existing weatherstripping, nominally sized to fit most doors without trimming, and can be trimmed to fit narrower widths when needed—all without taking the door off the hinges. A low-profile screw cover finishes the look and can be painted to blend with your door for a clean, “built-in” appearance. Durable black fins help hide scuffs and dirt for a neater entry day to day. Choose the size that matches your opening—32", 36", or 42"—and the finish that fits your style (white or black). Whether you’re tightening up a front door, a garage entry, or a busy mudroom, this under-door seal for exterior doors helps block drafts, dust, water, light, and pests for a more comfortable, cleaner home. If you’ve been searching for a “door sweep for bottom of door” or “front door weather stripping bottom,” this adjustable, trim-to-fit design delivers the fit, function, and finish you want in a 36 inch door sweep and beyond.
