Save your deck! You know those dark spots under the pots on your deck? That happens because water, dirt, bugs and grime are trapped under the pot. Left unattended that muck permenantly stains decking surfaces. The best defense is to prevent it from happening at all. Pot Pads™ can help.Pot Pads are discreet yet incredibly strong and are rated to hold up to 3,000 lbs. Just insert four Pot Pads beneath each pot providing instant drainage and aeration for healthier plants. Elevating the pot off of the decking surface prevents deck-rot, molding and staining, and will also keep pots from freezing and cracking during winter months. Using a unique two-part construction each Pot Pad is made of a hard plastic dome and a "non-skid" rubber grip pad. Pot Pads grip the underside of the pot creating suction and allowing for easy movement of the pot on hard surfaces. Recommended for patio gardening or deck gardening. For outdoor and indoor use.Four Pot Pads accommodate one medium or large size pot.
