What StrongBox Rack Mount Chassis does
StrongBox Rack Mount Chassis (legal entity: StrongBox Marketing) is a privately held American manufacturer of heavy-duty aluminum rack-mount enclosures, founded in 1980 and operated continuously from a single factory warehouse at 7660 Beverly Blvd in Los Angeles, California. The company's core differentiator is construction-grade aluminum thickness — 0.090-inch structural members made of 5052-H32 (side panels), 6061-T6 (front panels), and 3003 (covers) aluminum, more than twice the gauge used by typical competitors. Assembly uses stainless steel machine screws, lock washers, and captive PEM nuts that avoid galvanic reaction with aluminum and prevent vibration loosening, addressing failure modes common to carbon-steel-fastened competitors' products.
The product platform centers on a modular SB Series kit system (SB9 through SB24) covering six EIA-standard front panel heights from 3.5 to 12.5 inches and depths from 9 to 24 inches, augmented by E-Series Depth Extension Kits (0.5-inch depth increments), a compact 1U chassis variant (SBx-1 Series), a full line of interchangeable covers (perforated, solid, heavy cover plates) and accessories (bottom mounting plates, mounting angles, interior mounting panels), plus in-house Custom Kits services including laser cutting, N/C punch, welding, silk screening, UV printing, and custom finishes. Pricing is quote-based and not publicly disclosed; customers can order complete kits or individual parts through the company's catalog.
The customer base spans aerospace and defense primes (Boeing, Lockheed, Northrop, Raytheon, General Dynamics, Rockwell, Hughes, Northstar), U.S. military branches and government agencies (U.S. Navy, U.S. Air Force, FAA Technical Center, Los Alamos, Argonne, Brookhaven national labs), telecommunications and industrial majors (AT&T, GTE, Motorola, IBM, Unisys, Ford, GE, Bethlehem Steel, Westinghouse, Xerox, Reynolds Metals), research institutions (MIT), and broadcast technology (CBS Technology Center). The company sells direct-to-customer via website, phone, and email with F.O.B.-point shipping, a 30-day return policy on parts, and a no-time-limit warranty against defective workmanship. With 11–50 employees and no disclosed funding, M&A, or leadership changes, the firm presents as a mature, founder/owner-operated niche manufacturer.
