Premium Non Rubber Hardware - Dark Grey 2-Pk (Size 1) AWARD-WINNING DOORSTOP DESIGN : Jamm's unique design holds a door in BOTH directions when inserted securely under the end/skinny side of the door. Each door stop measures 5.1" L x 3.25" W and fits door gaps up to 1. **Measure your door gap BEFORE you purchase.** Works on all doors except doors with self-closing or lift off hinges. WEDGES DOORS LIKE NO OTHER: Other doorstops hold the door from one side only and are easily dislodged by a child, pet, breeze or accidental nudge; becoming a trip hazard or obstacle in the home. When wedged in securely Jamm holds the door from both sides so it does not dislodge easily. Measures 5.125" (L) x 3.25" (W) x 1" (H). WORKS ON ALL FLOOR SURFACES: Our anti-slip base and material choice provides superior gripping power and allows your door stoppers to work on all surfaces. Easy to use. Insert securely! Also available in JUMBO Size to fit doors hanging up to 1.38 inches off the ground. DOES NOT OBSTRUCT WALKWAYS: The placement of this door stopper at the end of the door rather than the side makes for a clear walkway. This creates a safer space and makes it easier for wheeling or carting things through doorways. A MUST HAVE for every home, office, business and toolbox! Great for trades and DIY projects such as painting or hanging a door; movers and decorators; hospitals and schools; hotels and museums - hardware for anywhere you need a door to remain securely open.
