Not every layout for a misting system will contain a place to attach every nozzle. In these situations alternative methods will be required. Risers are the perfect solution for areas like landscape beds. The lines are run under the ground then to the T fitting of the riser. Our regular copper risers come in 15" and 30" and use hard molded plastic stakes to keep the riser upright. The commercial risers are black anodized aluminum and come in 24" size and does not need a stake to keep them stabilized.
