Carter Y. ★★★★★ Oct 23, 2026

The stainless steel threads on this extension piece are cut clean and smooth, which made connecting it to my existing NPT base a breeze. Swiveling the arm into position feels solid and secure, exactly what I needed for holding a tablet in my truck.

Timothy ★★★★★ Oct 22, 2026

Finally got my tablet mount situated on the boat dash, and this swing arm extension gave me the perfect angle adjustment. The 1" NPT hole on the other end lined up exactly with my existing base, no adapters needed.

Samuel P. ★★★★★ Oct 20, 2026

Took a chance on this threaded extension for my marine radio mount, and the 1/2" NPT post threaded in perfectly with no wobble. The swing arm gives just enough flexibility to angle the device without loosening over time.
