Unique fingers securely lock into a range of panel sizes without use of locknut. Smooth, rounded interior edges for ease of installation. Limited intrusion into enclosure where access is tight. Rotation prevented when used in "Double D" mounting holes. Easy to install-no tools required. Ratchet design of sealing nut assembly provides superior anti-vibration and ensures a firm grip on the cable. Available in multiple sizes for cable diameters ranging from .210" (5,3 mm) to 1.260" (32,0 mm). We recommend using the fitting with the smallest maximum diameter that will fit your application. Meet UL strain relief requirements without bending or kinking the cable. Though similar in appearance and function to Heyco-Tite Liquid Tight Cordgrips, Snap-In Cordgrip Strain Reliefs may not be liquid tight at the panel interface.
