Access displays and meters in the clear upper compartment without disturbing power supplies and wiring in the lower compartment. The upper compartment’s hinged, latched cover swings open for fast, frequent access. The lower compartment has a removable, screw-secured cover—good for full access during setup or service, but not for frequent entry. All of these enclosures have a gasket that completely seals out swirling dust that's often created by grinding or drilling jobs.
