At 72 inches in overall length and 0.35 inches in diameter, this extension rod is built for accessing deep or difficult passages in HVAC, plumbing, and industrial maintenance applications. The female end is threaded 1\/4 inches NPSM to accept compatible brush and scraper handles, while the male end allows daisy-chaining with additional extensions. Fiberglass construction keeps the extension lightweight and resistant to corrosion, making it a durable choice for repeated service use.
