Tired of drafts, noise, and high energy bills? This showingo weatherstrip seal is a game-changer! Made from high-grade TPE (that's thermoplastic elastomer), it's crazy flexible, durable, and lasts way longer than cheap rubber seals. The 1/4-inch bulb diameter fits perfectly into standard 3/16-inch deep and 1/8-inch wide kerf slots on doors and windows. It comes in a 100-foot roll (brown color shown, but other colors available), so you can cut exactly what you need for any job. Installation is a breeze – just press the flange into the groove on your window or door frame. Boom – instant seal! It blocks out drafts, dust, and water, plus it reduces outside noise and helps keep your heating/cooling costs down. The top has a slick coating that makes windows slide easier and cleaning simpler. Perfect for refreshing old, warped windows or sealing up new ones. Whether it's for wood frame windows, casement windows, or doors, this stuff works wonders. Your home will feel cozier and quieter in no time!
