Single-gang aluminium extension box

The Bell 5406-0 is a weatherproof single-gang extension box made from die-cast aluminium. It provides a 9.5 cu-in capacity for wiring connections in outdoor or damp locations. The grey finish resists corrosion in exposed environments.

UL and CSA listed enclosure

The box meets UL and CSA standards for electrical safety. Its aluminium construction dissipates heat naturally without active cooling. No power draw or noise is produced by the passive enclosure.

Sustained load performance

Under continuous wiring load the aluminium body maintains structural integrity and thermal stability. The 1.00 in depth, 4.50 in length and 2.75 in width remain unchanged over time. The box suits installations that require a durable, code-compliant junction point.

Questions about this item

How do I install the 5406-0 aluminium extension box and what step is often missed?

Mount the single-gang box to a flat surface using the die-cast aluminium body, then fit a weatherproof cover; the step often missed is applying a gasket or sealant to maintain the weatherproof rating.

What maintenance or replacement will the 9.5 Cu-In aluminium box need over time?

Inspect the grey die-cast aluminium for corrosion and the gasket for cracking; replace the cover gasket if it hardens or the box if the threaded hubs strip.

What limit appears first on the 1.00 In deep extension box during sustained outdoor use?

The 9.5 Cu-In fill capacity is reached before the 1.00 In depth becomes restrictive, so conductor count is the first practical limit.
