Standard color black. Consult Heyco for white and other colors.
† Wire is not UL/CSA approved.
*Maximum Panel Thickness. Part has additional clearance. Consult Heyco for your Custom Finished Fit Panel Thickness.
**Use Elongated Mounting Hole.
***To install Strain Reliefs for .040" (1,0 mm) Maximum Panel Thickness use Part No. 0021 (No. R 291) Hand Pliers.

*To install strain reliefs for .040" (1,0 mm) maximum panel thickness, use Part No. 0021 (No. R-291) Hand Pliers.

• Protects the lifeline of your electric/electronic products by absorbing the forces of pull, push, and twist that may be exerted on the flexible power cord.
• Securely anchors, insulates, and protects cable at panel entry points.
• Sizes for thin .040" (1,0 mm) panel available: SR 4A-6 & SR 3A-4. See charts for details.
• Corresponding Mounting Hole Plugs can be used to fill blank/unused Mounting Holes and thus allow for a single panel design for multiple applications.
