Spool & Shackle Insulators
Spool & Shackle Insulators,The Workhorse of LV Distribution
Porcelain spool and shackle insulators for low-voltage distribution — secure conductor seating with grey or brown glaze per ANSI C29.4.

Reliable Insulation for Low-Voltage Lines
Spool insulators provide secure conductor seating on low-voltage distribution lines, while shackle insulators anchor conductors to structures. Both are manufactured to ANSI C29.4 with grey or brown glaze for long outdoor service.
Key Technical Advantages
Secure Seating
Deep conductor grooves hold LV conductors firmly.
ANSI Compliant
Manufactured per ANSI C29.4 for consistent quality.
Durable Glaze
Grey or brown glaze resists weathering and tracking.
Cost Effective
High quality at very competitive prices for volume supply.
