Freestanding Electronics Racks


Rack Shown with Accessories

Mount servers, automation controls, and computers in these open racks, they make it easy to organize and swap out components. Less bulky than electronics cabinets, you can line up these racks to maximize limited storage space. Each rack has two pairs of grounding studs that create a path for static electricity and protect components from electric shocks.

All are compatible with standard 19" wide components. One rack unit is 1.75" high.

UL 2416—Freestanding electronics racks meet UL 2416 so they're rated for use in server rooms and other IT, AV, and telecom installations.

Mounting Brackets

Image of Product. Front orientation. Brackets.

Use mounting brackets to secure lightweight accessories, such as routers, that can’t mount directly to the rack because they’re less than 19" wide. Unlike shelves, brackets leave the bottom of accessories exposed, which can make accessing them easier. To attach accessories, add your own mounting holes—these brackets are thin enough to drill through easily.

DIN Rails


DIN 3	DIN 3 Rails with Bracket

DIN 3 Rails with Angled Bracket	Drill-Your-Own DIN 3 Rails with Centerline

Drill-Your-Own DIN 3 Rails	DIN 1

DIN 2

Mount terminal blocks, relays, and other devices onto flat surfaces. These rails are often used in electrical enclosures, server racks, and equipment cabinets.

DIN Rails with Bracket—Create extra space between the rail and the mounting surface to fit bulky devices or route wires.

DIN Rails with Angled Bracket—Mount equipment at an angle while adding space behind it. The tilted rail makes labels and displays easier to view, especially in crowded enclosures.

Centerline—Keep mounting holes lined up as you drill along these rails.

Drill-Your-Own DIN Rails—Add mounting holes only where you need them.

304 Stainless Steel—The best choice for equipment that’s regularly washed down. These rails resist corrosion from water and mild chemicals.

Aluminum—Lightweight and corrosion resistant. These rails hold up in wet environments almost as well as stainless steel, but they’re not as strong.

Zinc-Plated Steel—Strong and durable. These rails have zinc plating to protect them from occasional exposure to moisture.

DIN Rail Trade Size—We gave each type of rail a trade size to help you quickly find compatible parts. DIN 3 is the most common type of rail—it's also called top hat or standard rail. DIN 2 is a smaller version of DIN 3, so it's also known as mini rail. DIN 1 is also known as G-section rail.

Heavy Duty Electronics Cabinets

These cabinets accommodate up to 3,200 lbs. of equipment and have larger interiors than standard electronics cabinets. Use them to house large-size automation controls, data communication, and networking equipment. The front and rear doors are perforated for ventilation and visibility. Both doors are lockable and include two keys. They are keyed alike (all open with the same key). Cabinets have two sets of depth-adjustable mounting rails and an open bottom for cable exit as well as ventilation.

Shelves—Shelves can be mounted at any level.

Electronics Rack Equipment Installation Supports

Shelve your worries about dropping heavy and valuable rack components, from servers to router shelves. These supports create temporary ledges to let equipment—and your arms—rest as you set up your electronics rack. Each pack includes four supports, one to prop up each corner of the equipment. Simply snap them into the rack’s rail just below the level where you want to mount equipment. When you’re done installing, pop them right out.

Magnetic-Back DIN Rails

Quick to install and easy to reposition, these rails mount to steel enclosures with a strong magnet. Since you don’t need to drill holes to install them, they help you avoid leaks in liquid-tight enclosures. They’re also good for tight spaces where a screwdriver won’t fit.
