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.
Spool & Shackle Range
53-series spool insulators and shackle insulators in grey or brown glaze.
