This is an 18 inch Pool Safety Cover Pipe Anchor that includes a threaded brass anchor. The 18 inch pipe anchor is designed for pools with paver decks, loose brick or garden/lawn areas near the pool with loose terrain. Pipe anchors extend holding power of a regular screw-type anchor down 18 inches into the solid ground. Use the 18 inch pipe anchor to give more stability in looser soils and terrain.
Pipe anchors are aluminum tubes with a brass screw-type anchor permanently embedded into one end. Pipe anchors can be installed by pre-drilling a 15/16 to 1 inch hole into the ground and through loose bricks or patio stones when necessary. Place a block of wood over the top of the pipe anchor assembly (or use a rubber mallet) to gently tamp into place.
