MIDDLE ATLANTIC

Middle Atlantic Products, founded in 1979 and headquartered in Fairfield, New Jersey, is a manufacturer of rack, enclosure, and mounting solutions for professional audio/video, broadcast, security, and industrial control applications. The company’s product line includes equipment racks, rack-mount shelves, power distribution units, cable management systems, and hardware accessories such as screws, cage nuts, and washers. Middle Atlantic is known for its adherence to industry standards like EIA-310 for rack spacing and UL listing for certain power products, though specific certifications vary by SKU. Their racks and enclosures are typically constructed from cold-rolled steel with powder-coat finishes, offering load capacities up to 2,500 lb for select models. The brand also provides thermal management accessories, including fan panels and vented doors, to support equipment cooling in enclosed spaces. 3G Electric supplies a range of Middle Atlantic hardware and accessories, including utility panel shelves (e.g., model U1), cage nuts with #10-32 thread screws (e.g., CN1032-50), and captive cup washers (e.g., HW100). These components are designed for use in standard 19-inch racks and enclosures, supporting secure mounting of equipment such as amplifiers, processors, and control panels. The cage nuts and screws are available in various thread sizes and pack quantities, allowing procurement specialists to match hardware to specific rack rail thicknesses and equipment requirements. 3G Electric’s inventory includes both common and less-common Middle Atlantic SKUs, enabling maintenance managers and plant engineers to source replacement or expansion hardware without long lead times. For industrial environments, Middle Atlantic’s rack accessories are often specified in control rooms, server closets, and broadcast facilities where vibration resistance and consistent thread engagement are critical. The brand’s utility shelves, like the U1, provide a flat mounting surface for non-rack-mountable equipment, with a 1U height that fits standard rack spaces. By stocking these items, 3G Electric supports global customers in maintaining standardized rack infrastructure across multiple sites, reducing the need for custom fabrication or adapter plates.

Frequently asked questions

Common questions about MIDDLE ATLANTIC from 3G Electric.

What thread sizes are available for Middle Atlantic cage nuts and screws?

Middle Atlantic cage nuts and screws are commonly available in #10-32 thread size, as seen in the CN1032-50 model. This thread size is standard for 19-inch rack rails in EIA-310-compliant enclosures. Other thread sizes, such as 12-24 or M6, may be available depending on the specific SKU. Always verify the thread size against your rack rail and equipment mounting holes before ordering.

Are Middle Atlantic utility panel shelves like the U1 rated for specific load capacities?

Middle Atlantic utility panel shelves, such as the U1 model, are designed to support equipment placed on them within a standard 19-inch rack. While the manufacturer does not publish a universal load rating for all shelves, typical 1U shelves can support up to 50 lb when properly mounted. For heavier equipment, consider using Middle Atlantic’s heavy-duty shelves or sliding shelves with higher load ratings. Always check the product datasheet for the specific shelf model.

Can Middle Atlantic cage nuts be used with non-Middle Atlantic racks?

Yes, Middle Atlantic cage nuts with #10-32 threads are designed to fit standard 19-inch rack rails that accept square or round mounting holes, as per EIA-310 specifications. They are compatible with most brands of racks and enclosures that use the same hole pattern and thread size. However, verify that the rack rail thickness and hole shape match the cage nut design (e.g., square-hole racks require square cage nuts).

What is the difference between Middle Atlantic captive cup washers and standard flat washers?

Middle Atlantic captive cup washers, such as the HW100 model, feature a cup-shaped design that retains the screw head and prevents the washer from falling off during installation or removal. This is useful in rack applications where screws are frequently inserted and removed, reducing the risk of dropped hardware inside equipment. Standard flat washers do not have this retention feature and may require separate handling.

Does Middle Atlantic offer any corrosion-resistant hardware for industrial environments?

Middle Atlantic hardware, including screws and cage nuts, is typically made from steel with a zinc-plated or black oxide finish for moderate corrosion resistance. For environments with high humidity or chemical exposure, stainless steel hardware may be required, but Middle Atlantic does not widely advertise stainless options in their standard catalog. For such applications, consider using aftermarket stainless steel cage nuts and screws that match the #10-32 thread size.
