Product Description 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. #productDescription { color: #333333; word-wrap: break-word; font-size: small; line-height: initial; margin: 0.5em 0px 0em 25px; } #productDescription_feature_div > h2.default { font-size: medium; margin: 0 0 0.25em; } #productDescription_feature_div > h2.books { color:#333 !important; font-size:21px !important; line-height: 1.3; padding-bottom: 4px; font-weight: normal; margin: 0px; } #productDescription_feature_div > h2.softlines { color:#333 !important; font-size:21px !important; line-height: 1.3; padding-bottom: 4px; font-weight: bold; margin: 0px; } #productDescription > p, #productDescription > div, #productDescription > table { margin: 0 0 1em 0; } #productDescription p { margin: 0em 0 1em 1em; } #productDescription h3 { font-weight: normal; color: #333333; font-size: 1.23em; clear: left; margin: 0.75em 0px 0.375em -15px; } #productDescription table { border-collapse: inherit !important; margin-bottom: 0; } #productDescription table img { max-width: inherit !important; } #productDescription table td { font-size: small; vertical-align: inherit !important; } #productDescription ul li { margin: 0 0 0 20px; } #productDescription ul li ul { list-style-type: disc !important; margin-left: 20px !important; } #productDescription ul ul li { list-style-type: disc !important; margin-left: 20px !important; } #productDescription > ul ul li { list-style-type: disc !important; } #productDescription ul li ul li { margin: 0 0 0 20px; } #productDescription .aplus p { margin: 0 0 1em 0; } #productDescription small { font-size: smaller; } #productDescription.prodDescWidth { max-width: 1000px } P.when('jQuery').execute(function($){ $("#productDescription table").each(function() { var width = $(this).attr('width'); if (width) width += 'px'; else width = 'auto'; $(this).css('width', width); var padding = $(this).attr('cellpadding'); if (padding) padding += 'px'; else padding = '0px'; $(this).css('padding', padding); }); }); #productDescription h3 { margin: 0.75em 0px 0.375em -1px; }
