The Techspan RDC21NA is a 3/4" NPT nylon cord grip designed for securing and sealing cables where reliable strain relief and environmental protection are critical. Moulded from high-strength Polyamide 6 (PA6), this dome-style connector handles cable diameters from 0.51" to 0.71" and delivers IP68 (5 Bar) and IP69K dual ratings — making it equally at home in wet industrial environments, outdoor enclosures, and washdown applications. The included O-ring and locknut ensure a watertight, vibration-resistant seal right out of the box, saving installation time on the job site. UL-listed (E360400), the RDC21NA is a practical, code-compliant choice for panel builders, industrial electricians, and OEM assemblers who need consistent performance at volume.
