All our receptacles are made of 100% recyclable metal. They are zinc plated and powdered coated to be weatherproof. Can be bolted to the ground or with a metal cable.
The receptacles have a built in area on the base that can be used to bolt down the receptacles to prevent theft. The second option is to secure them with a metal cable and lock using the back hoop in the receptacle.
The receptacle can be cleaned using water and soap. It is recommended to first check a small area before using any chemical cleaning solutions in order to avoid damage.
