The TN-375 is a Tinnerman nut designed for speed mounting of terminal blocks that lack mounting positions. This fastening accessory is specifically engineered for long feed-through applications and features a robust construction with precise dimensional tolerances. The nut accommodates the mounting requirements of Curtis Industries terminal block series, including Series CB/CFT and Series 43000, enabling quick and secure installation without the need for dedicated mounting holes on the terminal block itself. It is commonly used in industrial control, electronic feed-thru, and high-density wiring applications where space efficiency and rapid assembly are critical.
