Block Division

What Block Division does

Block Division, Inc. is a U.S. manufacturer of small pulley blocks, sheaves, and related accessories, founded in 1960 by Lloyd Sutton and headquartered in Wichita Falls, Texas. The company produces mechanical block-and-tackle pulley systems in eight primary configurations (swivel eye, flat mount, fixed eye, swivel hook, deck, bolt, strap, and deadman) across single, double, and triple sheave variants, with materials spanning galvanized clear zinc and stainless steel for corrosion resistance. Its core technology is precision-machined metal hardware with closely controlled alloy compositions to ensure consistent load-bearing safety and durability, supported by an in-house quality control process the company highlights as a key differentiator. The product portfolio includes replacement components (sheaves, bushings, bearings) and specialty items such as matte-black Mule Blocks for theater and movie rigging.

Block Division sells primarily through a direct-to-consumer e-commerce storefront on blockdivision.com, supplemented by a digital flip catalog, social media channels, and a quote-request workflow for larger orders. Pricing is per-unit and varies by material finish, sheave count, and working load limit, with galvanized zinc items starting at $7.12 and stainless steel premium variants reaching $367.46. Same-day shipping is offered for orders placed before 1 PM CST, with 24-hour fulfillment thereafter, indicating an in-house or near-shored logistics operation. The company has held government cage codes since the 1970s and serves federal procurement channels alongside commercial customers.

Customer segmentation spans at least eight verticals: agriculture, marine, construction, entertainment (movie/stage/theater), commercial and industrial, accessibility and handicap rigging, field and ranch operations, and transportation. The 11-50 employee organization is privately held with no disclosed institutional investors, funding rounds, mergers, acquisitions, or leadership transitions since founding. Operational continuity is signaled by active copyright dates through 2026 and maintained Better Business Bureau accreditation in the Dallas region.
