15 Hand-Selected Franchise Lines.
We don't list everything — we list what works. Each manufacturer below earned its place through franchise authorization, quality certification, cross-reference coverage, and proven supply reliability. Asian engineering, held to American standards.
Franchise Authorized
Every line is a direct franchise agreement — no gray market, no brokers, full manufacturer traceability on every reel.
Vetted to American Standards
We screen each manufacturer for UL, RoHS, IATF and AEC-Q certification, plus factory audits before they join the line card.
No Competing Lines
We never carry direct competitors within a category — so each partner gets our full commitment, and you get straight answers.
