Rugged, diecast aluminum alloy (tough yet easy to machine), electronic instrument enclosure. Two piece “tongue & groove” construction with a replaceable one-piece silicone rubber gasket provides protection against access of dust and water. Gasket supplied loose inside the enclosure (not pre-installed). Ideal for repetitive opening and closing. Easy to wall mount using “through box - blind hole” construction, outside of gasket protection. Designed to meet IP68.
