Aluminum Boxes | McMaster-Carr

Lighter than stainless steel yet durable, these aluminum enclosures protect electronics from frequent washdowns and withstand periodic submersion in water.

Machine-Mount Aluminum
Submersible Enclosures

Attach these enclosures to machine control panels or walls to guard electronics within the enclosures from water in wet and washdown areas. You can mount them without removing the cover and exposing electronics, such as sensors, switches, and circuit boards, to the environment.

Aluminum Weather-Resistant
Enclosures

Made of aluminum, these enclosures resist corrosion from rain, sleet, and snow. While not as corrosion resistant as stainless steel, aluminum is lighter for better mobility, and also easier to machine for custom mounting.

Weather-Resistant
Enclosures with Cooling Fans

Fans built in to these enclosures keep electronics at the temperature you set, and the filtered intake and exhaust let cool air flow through the enclosure without letting water and contaminants in.

EMI/RFI-Shielded Enclosures

These enclosures reduce electromagnetic interference (EMI) and radio frequency interference (RFI), which can cause electrical problems like flickering monitors, interrupted data signals, and unwanted radio noise.

Hazardous Location Enclosures

For use in hazardous locations, these enclosures are rated NEMA 7 and 9 and meet UL Class I, Divisions 1 and 2, Groups B, C, and D; Class II, Divisions 1 and 2, Groups E, F, and G; and Class III, Divisions 1 and 2.

DIN-Rail Mount Enclosures

Snap these enclosures onto 35 mm DIN rail and lock them in place.

DIN-Rail Mount
Washdown Enclosures

These enclosures shield electrical components from water, so they’re safe to install onto DIN rail in wet and washdown environments.

Outlet Strips

Often used in offices and workstations, these outlet strips power multiple devices from a single wall outlet.

Outlet Strips with
Individual Outlet Switches

Separately control each device plugged into these strips—each outlet has its own power switch.

Outlet Strips with Remote Switch

The power switch to these outlet strips is on a 44" long cord, so you can control power even when the strips are in hard to reach places, such as under a desk.

Sure-Grip Outlet Strips

Also known as hospital-grade outlet strips, these outlets have an extra-tight fit to prevent plugs from detaching. They are marked with a green dot.

Cabinet-Mount Outlet Strips

Install these extra-long strips onto the frame of an electrical cabinet.

3D Printer Air Filtering and Conditioning Enclosures

3D Printer Air Filtering and
Conditioning Enclosures

Protect the health of nearby workers and maintain ideal operating conditions for your 3D printer. To keep your workspace's air clean, these enclosures filter harmful fumes, VOCs, and ultrafine particles that are common when working with filaments such as ABS and nylon.

Mailboxes

Send, receive, or collect mail or packages at your facility with these USPS (United States Postal Service) approved mailboxes. Made of powder-coated aluminum, they won’t corrode when exposed to harsh weather.
