Standoff Insulators

Standoff insulators from Cal Fasteners are ideal for electrical panels, bus bars, and switchboards. Manufactured from special high-strength, glass-reinforced polyester bulk molding compound (BMC), these electrical insulators meet requirements for UL891 safety standards and are UL listed 94-VO for flammability.
 
We offer standoff insulators in a range of heights, thread sizes, and configurations. Custom sizes and shapes are also available. All insulators come standard with aluminum inserts; brass or steel inserts are available upon request.
 
All our insulators are hi-pot tested at 3,000 volts, and are inspected for defects, cracks, and short spots.
 
We also offer centerpost insulators and switchboard insulators.
