These signs are not suitable for hard stone-kind of floors. Their main purpose is to easily install in a yard, lawn, or garden. Our LawnBoss signs come as a kit containing a durable aluminum sign, a bend-proof steel stake, and the hardware necessary for mounting. A tapered end makes it easy to install the stake into the soft or slightly harder grounds while anti-twist flanged tabs at the bottom provide extra support. Installing the sign only requires you to push the tapered pointy end of the stake into the ground. A harder ground will perhaps need a hit or two from a hammer. Please watch this short video that shows just how easy it is to assemble and install our LawnBoss signs.
