With thoughtful execution and striking good looks, The Sentry Doorstop stands guard, ever-vigilant. When the door absolutely must stay open, the Sentry Doorstop will see to it. Composed of 3 lbs of stainless steel, and outfitted with a rubber base, even the heaviest doors will be kept at bay. The Sentry Doorstop is encircled by two silicone rings that act as bumpers to protect precious Paintjobs. A loop of rubberized mesh webbing makes moving it around a breeze.
