McCullough Industries

What McCullough Industries does

McCullough Industries is a Kenton, Ohio-based manufacturer of heavy-duty steel self-dumping hoppers and related material handling equipment, operating under the Wright® brand. Founded around 1960 with 60+ years of continuous operations, the company designs and fabricates a broad portfolio including GEN II Self-Dumping Hoppers (over 30 standard models ranging from 1/4 to 6 cubic yards and 4,000–7,000 lb load ratings), Low Profile Dumping Hoppers, Bump Release Hoppers with hands-free automatic dumping, Wright Quick Attach Hoppers for direct loader integration, Stackable Rotating Totes (SRTs), Front Dump, Hooded, Dust Collection, and Open Sided Hoppers, plus Spill Containment Platforms with EPA/OSHA-aligned design. Core technology is heavy-gauge welded steel construction with continuous welds for leak prevention, balanced dumping geometry, and formed top edges — yielding over 1,000 product variations across gauge (7-gauge, 11-gauge, 1/4-inch), capacity, and accessories.

The business model is hardware sales of quote-priced, custom-configured steel equipment to industrial buyers, served both directly (contact forms, phone at 800.245.9490) and via an extensive reseller network that includes Grainger, McMaster-Carr, MSC Direct, Zoro, Global Industrial, Solution Dynamics, Nationwide Industrial Supply, Material Flow, Industrialhoppers.com, One Monroe, and Material Handling Systems Inc. (Rackman). The company is structured as a member of the Olympic Steel Family of Brands, with Olympic Steel acting as both parent and distribution partner; no independent funding, M&A, or institutional investor activity is disclosed. Target customer segments are manufacturing (metalworking, fabrication, industrial production), construction (debris collection, site cleanup), recycling operations, and food service — with manufacturing and construction flagged as primary verticals. The firm is privately held, reports 1–10 employees in firmographic data, operates a single manufacturing site in Kenton, OH, and does not disclose revenue.

Brands

• Wright®: Brand name for McCullough Industries' self-dumping hoppers and material handling equipment, including Wright GEN II series, Wright Quick Attach Hoppers, and Wright Stackable Rotating Totes

Products and services

• Wright GEN II Self-Dumping Hoppers Heavy-duty welded steel self-dumping hoppers designed to roll forward when loaded, dump completely, and automatically return to upright locked position for reloading. Available in 1/4 yard to 6 yard capacities with 4,000 to 7,000 lb weight capacities. Used by manufacturing, construction, and industrial facilities for storing, transporting, and dumping bulk materials with forklift.
• Low Profile Dumping Hoppers Low-profile self-dumping hoppers with reduced height (17–24 inches) for height-restricted workspaces such as low-clearance production areas and jobsites. Wide design provides increased capacity. Available in 1/4 to 1.5 cubic yard capacities with 4,000–5,000 lb weight capacity.
• Bump Release Hoppers Self-dumping hoppers that automatically dump when the bump plate makes contact with a roll-off container, enabling hands-free operation. Spring-loaded release triggers dumping and the hopper automatically returns to upright position. Designed for safety and economy in industrial environments.
• Wright Stackable Rotating Totes (SRTs) Forklift-compatible steel totes that stack securely for space savings while rotating open for easy access. Improve organization, transport, and overall safety in material handling. Available in 1/3 to 1.5 cubic yard sizes with 2,000 to 4,000 lb weight capacity.
• Wright Quick Attach Hoppers Hoppers designed to connect directly to quick tach plates on loader lift arms, using built-in hydraulics for dumping without additional accessories. Available in 1.5–2 cubic yard capacities with various gauge options. Built for efficiency, near-effortless dumping, and exceptional portability in field applications.
• Front Dump Hoppers Durable containers with front-release Easy-Pour gate design for smooth, controlled dumping of bulk materials. Available in 1–5 cubic yard capacities with up to 7,000 lb weight capacity. Collect, transport, and dump bulk materials with safer and more efficient handling than overhead tipping.
• Hooded Hoppers Steel hoppers with heavy-duty hoods that keep contents contained, preventing materials like glass, scrap, or steel banding from bouncing or spilling during loading. Rated up to 6,000 lbs. Protects materials, reduces spillage, and ensures safer, more efficient handling.
• Dust Collection Hoppers Sealed, watertight hoppers designed to capture and contain fine dust and particulate from industrial processes. Feature integrated dust collection system compatibility for controlled disposal. Improves air quality and makes disposal of collected dust safer and more efficient.
• Open Sided Hoppers Self-dumping hoppers with accessible side openings for quick loading and unloading of bulky or irregular materials. Available in 1.5 cubic yard capacity with 6,000 lb weight rating. Open design improves efficiency while maintaining safe, reliable material handling.
• Spill Containment Platforms Barrel hoppers built from 7-gauge steel for capturing leaks, drips, and spills. Available in 1, 2, and 4 barrel capacities (up to 163 gallons) with drain holes and removable grating tops. Designed to support EPA and OSHA compliance for spill management.
