Quadrangle Products

What Quadrangle Products does

Quadrangle Products Inc. is a privately held U.S. custom cable assembly manufacturer founded in 1985 and headquartered in Englishtown, New Jersey. The company specializes in custom-designed cable assemblies that interface with flat-panel displays and peripherals, with a product portfolio centered on LVDS cables, flat flexible cables (FFC), flexible printed circuits (FPC), micro-coaxial assemblies, MIL-SPEC connector cables, custom wire harnesses, adapter boards, and development kits for rapid prototyping. Supporting capabilities include precision FFC notching and slicing, in-house die and fixture manufacturing, and 100% electronic testing for continuity and pin orientation on all custom cable assemblies. The company maintains a design library of over 10,000 unique cable designs with unique bills of materials, supports more than 2,100 connector types, and holds over 100,000 individual FFCs in inventory. All cables are manufactured to IPC/WHMA-A-620 standards using UL and CSA approved components.

Quadrangle's customer base spans defense and military, medical, aerospace and aviation, marine, transportation, industrial, IT, and telecommunications sectors, with explicit ITAR certification enabling defense and export-controlled work and ISO 9001:2015 quality management certification covering wire harnesses and custom cable assemblies. Primary end-uses include GPS systems, rugged display monitors, mobile computing, cockpit displays, in-flight entertainment, medical imaging and patient monitoring equipment, and digital signage.

The business model is sales-led and project-based: application engineers serve as the sales team, providing free engineering support from concept through custom quote to final production. Pricing is quote-based with no minimum order quantity in most cases and prototype lead times of 1-2 weeks; standard FFC products carry a 500-piece MOQ and micro-coax products a 10-piece MOQ. Orders are submitted via email or fax with purchase orders, and distribution is entirely domestic (United States) through a direct sales team and website-driven quote requests. Marketing relies on educational content (custom cable guides, LVDS/FFC guides, blog posts), email newsletters, and industry event participation, notably SID Display Week.
