Outlet bodies handle compact pulls and branch connections. GUB boxes provide accessible space for instruments or terminals. Bolted enclosures suit larger control assemblies and field layouts. Size the enclosure for conductor fill, bending space, device heat and the certified entry arrangement.
Explosion-Proof Junction Boxes & Enclosures in Canada
Choose a hazardous-location enclosure from the job it must do and the complete marking it must carry. Outlet bodies suit compact conductor pull and branch points. GUB instrument enclosures provide access for terminals, relays or instruments. Bolted enclosures provide more internal space for control assemblies. Under CEC Section 18, the exact box, fittings, conduit or cable entries, gas or dust group, surface temperature and environmental rating must all suit the classified location. NEMA 7 or 4X describes enclosure performance; it does not replace a Canadian approval mark or the Zone or Division marking. Send the classification drawing, entry sizes, device heat load and required material so we can identify a configuration and documentation package for review.

Select by function, space and entry plan
Competitor catalogues make it easy to compare hub counts and materials. A project-ready selection must also account for conductor fill, bending space, device heat, certified entries and the complete hazardous-location marking.
- 1
Outlet body
For compact pulls, splices or branch points where the certified entry arrangement and working space are sufficient.
- 2
GUB enclosure
For instruments, terminals or relays that need accessible internal space and a defined hub arrangement.
- 3
Bolted enclosure
For larger control assemblies, more conductors or layouts that need additional usable volume and access.
- 4
Documented configuration
Cast aluminum and cast iron alloy bodies, NEMA 7 and IP66 ratings, factory-tapped NPT entries from 1/2" to 4", and assembled device options.
