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.

Mount terminal blocks, power supplies, relays, and other control and distribution devices on walls and other flat surfaces and in enclosures.

DIN Rails with Bracket—DIN rails with a bracket create extra space behind them to accommodate bulky items.

DIN Rails with Angled Bracket—DIN rails with an angled bracket are tilted, letting you fit more of them into a vertical space. For easy access, position high-mounted devices so they’re tilted downwards and low-mounted devices so they’re tilted upwards.

DIN Rails with Centerline—On DIN rails without mounting holes, drill holes where you need them. Rails with a centerline guide where you should drill.

DIN 3—DIN 3 is the most commonly used 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

Mount and reposition components without drilling leaky holes in your steel enclosure—a strong magnet holds these DIN rails in place. Since they install without screws, they fit in spaces that are too small for a screwdriver.

UL 94 V-0—DIN rails meet UL 94 V-0, so if they catch fire, they’ll self-extinguish within 10 seconds and won’t spread the fire by dripping.

Adhesive-Back DIN Rails


1 lb. Capacity	16 1/2 lb. Capacity

Stick this DIN rail in any enclosure to mount components without making screw holes that might leak. The adhesive backing and short length let you install these in tight spaces where a screwdriver wouldn’t fit. Adhesive reaches full capacity after 24 hours.
