WOOD
Just screw them in, you don't even need to drill a hole - how easy is that?

DRY WALL
Just as you would with pictures or mirrors, use a drywall anchor and screw

Stucco, Brick, Stone, and Masonry
For block brick, stucco, or stone walls, drill holes 1" deep by 1/4' wide, using a masonry drill bit. Insert 1/4" plastic anchors and tap flush with masonry surface, or use the Tapcon, commonly known as the "blue screw" (available at any hardware store; Tapcon sells the right drill bit for each size screw.) It's easy and will take about 30 seconds to install.

Wrought Iron, Lattice, Trellis, and Chain Link
The easy way to install Hang-A-Pot™ on these materials is by using self-locking nylon ties (called "calbe ties or "tie wraps"), which are available in the electrical section of your local hardware or home improvement store. Copper wire can also be used. For wrought iron, be sure to affix the ties or wire at the intersection of the horizontal and vertical sections. Alternately, you can dril a 1/8" hole in the iron and use self-tapping stainless steel screws (#8) to install Hang-A-Pot™.

Aluminum Screened-in Enclosures, and Greenhouses
Tap a small starter hole with punch or awl, or drill a small starter hole with an electric drill. Then screw in your Hang-A-Pot™ using the self-tapping stainless steel screws included with your Hang-A-Pot™.
