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.
