1-Inch Hub Deep Device Box
This single-gang aluminum box provides a 1-inch threaded hub for conduit entry. The FD-type enclosure suits industrial and commercial wiring where a deeper cavity is required. Gray finish resists corrosion in damp or outdoor locations. Internal grounding screw simplifies equipment bonding.
47 Cubic Inch Capacity Frees Conductor Space
Deep 2-inch body yields 47 cubic inches of wiring volume, easing pull-through and splice room for larger conductors. Tapered threads on the hub ensure a tight seal when paired with matching conduit fittings. Mounting holes on 1-inch centres align with standard straps and brackets. Aluminum construction dissipates heat without adding excessive weight.
Handles Heavy Conduit Runs, Not Multi-Gang Layouts
The single inlet and single-gang format limit use to straight or terminating runs rather than branching circuits. Builders needing multiple device openings or larger hub diameters must select a different enclosure. Capacity tops out at 47 cubic inches, so very large conductor counts or numerous splices may exceed fill allowances.
