Bell Mouth Strain Relief Bushings – 15.9mm Mounting Hole Diameter , 14mm Panel Thickness , 8.2mm Min to 9.1mm Max Cable Diameter | Vital Parts – STRB266R

Bell Mouth Strain Relief Bushings are part of the original Heyco range and serve as a cost-effective alternative to the Lockit style variants. Designed for use with pliers during installation, these bushings improve cable life by holding wires securely in place and preventing sharp bends or kinks. The flared bell mouth provides a smooth, gentle exit that guides cables into a relaxed bend, reducing stress at the cable entry point.

What are Bell Mouth Strain Relief Bushings?

Bell Mouth Strain Relief Bushings are panel-mounted inserts that grip and support electrical cables as they exit enclosures or equipment. Manufactured from UL94V-2 rated Nylon 6/6, they are suitable for Round cable types. These bushings help absorb vibration and pull forces, protecting cables from wear and prolonging product life. They are ideal for electronics, control panels and machinery where secure, neat cable routing is required.
