4-11/16 x 4-11/16 in Metal Junction Box 2-1/8 in Deep - 8 Pack

In this review the focus is on a practical pack of eight metal electrical junction boxes intended for installers and DIYers who need reliable, repeatable junction points. The reviewer found the biggest selling point to be the combination of generous internal volume and robust galvanized steel construction, which together make these boxes suitable for common residential and light commercial wiring tasks. The assessment is based on how the boxes perform during installation, their knockout flexibility, and whether the 40.2 cu. in. capacity truly prevents overcrowding when multiple conductors and connectors are used.

Key Features

• Pack Quantity: A set of eight boxes provides value and consistency for multi-point projects or follow-up installations.
• Spacious Capacity: The 40.2 cu. in. interior gives enough room to avoid wire crowding and simplifies arranging connectors and pigtails.
• Galvanized Steel Construction: The drawn steel body resists deformation and offers durability for repeated handling and long-term use.
• Multiple Knockouts: Several 1/2 in and 3/4 in knockouts and TKOs make routing common conduit and cable sizes straightforward and fast.
• Standard Footprint: The 4-11/16 in square face and 2-1/8 in depth match typical 4 in box layouts, easing device and cover compatibility.

Who It's For

This pack is aimed at electricians, contractors, and experienced DIY homeowners tackling renovations, additions, or new builds where multiple junctions are required. The volume and knockout variety suit common household circuits and most receptacle or switch assemblies.

Those who should look elsewhere include installers who need shallow-profile or specialty boxes for low-clearance retrofits, or projects requiring nonmetallic or weatherproof enclosures. For those specific needs a different box type is more appropriate.

Pros & Cons

Pros

• Good build quality from galvanized steel gives durable boxes that resist minor impacts and handling.
• Large 40.2 cu. in. capacity reduces risk of overcrowded conductors and makes wiring and connector placement easier.
• Multiple knockout sizes provide flexible entry options for both conduit and cable runs during installation.
• Eight-count packaging offers value for multi-point jobs or stocking a service vehicle.

Cons

• The standard 2-1/8 in depth may be too deep for some tight retrofit situations where shallower boxes are required.

Our Verdict

These galvanized steel junction boxes are a practical, cost-effective choice for most interior electrical work where a standard 4 in box footprint is required. The roomy 40.2 cu. in. interior and multiple knockouts simplify wiring and reduce installation time, while the eight-pack format suits builders and service techs. They are not the solution for shallow retrofit cavities, but for general wiring and renovation tasks they represent good value and dependable performance.
