Rugged Enclosure
This enclosure is constructed of durable, marine grade anodized aluminum with two coats of epoxy. Optional clear polycarbonate cover enables observation of circuit status without opening the enclosure.

Hazardous Approval Ratings
The JM may be used in explosion proof and general purpose applications.

Quick Access
Screw-on cover enables convenient access to the enclosure.

Vapor Tight and Submersible
Rated for IP67 and NEMA 4, 4X and 6, the JM withstands rigorous wash downs and corrosive environments.

Compact Design
The enclosure’s size minimizes space requirements for wiring and conduit layout.

Wide Variety of Functions
Select from drop connectors, switched drop connectors, relay modules, I/O modules, power conditioners, and special module configurations.

Convenient Wiring
Experience quick and secure wiring with the clearly labeled, top insertion terminal strips.

No Seal-Offs in Division 1 & 2 Hazardous Areas
Eliminate costly seal fittings in Class I & II division 1 & 2 areas when installing bus networks using StoneL’s JM enclosures. Because the JM enclosure has passed special pressure piling tests simulating the extreme pressures caused by remote conduit ignition, no seal offs are required in either Div 1 or Div 2 areas. 

Keep Bus Energized During Maintenance
in Division 1 Areas FM approved factory-sealed leads are available for the drop leg of the switched drop connector. In division 1 areas the conduit must not be opened to atmosphere when wires are energized. However, with factory sealed leads no energized wires are exposed to the atmosphere when the drop leg is opened or removed for maintenance even though the bus trunk remains energized.
