AWARD-WINNING DOORSTOP DESIGN : Jamm's unique design holds a door OPEN in BOTH directions when inserted securely under the end/skinny side of the door. Measures 5.1" L x 3.25" W and fits door gaps up to 1". MEASURE YOUR DOOR GAP BEFORE YOU BUY. Works on all doors except doors with self-closing or lift off hinges.

PLEASE READ THIS SECTION CAREFULLY : Measure BEFORE you buy! Refer to photos for measurements. Not all door gaps are the same size, therefore we manufacture this doorstop in 2 sizes. To check which size you need please place a nickel coin on its edge and try to push it under the door (see the photo in the listing). If it fits under your door then you need the JUMBO version of this doorstop. To see this listing please copy and paste this link: https://www.amazon.com/dp/B019AP1Q7Q

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. 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.
