NGP Adjustable

Our adjustable and spring loaded perimeter door seals from National Guard Products offer maximum protection from the outdoor elements by maintaining constant pressure along the full height of your door. As the gap between your door and jamb fluctuates slightly, you simply adjust the screw or spring loaded pressure of the perimeter seal to create a perfect seal and eliminate the need to re-position the mounting location.


Offering easy installation and a tight, weather-resistant seal every time, HarborCitySupply.net proudly offers NGP adjustable and spring loaded perimeter seals to protect your home or commercial building from drafts, moisture, and debris trying to infiltrate your interior space.
