Jameson fiberglass poles have been an industry standard for over 50 years. B-Lite hollow core fiberglass poles are commonly used in the tree care and landscaping industry for general pruning. B-Lite fiberglass poles are super lightweight, very strong and rigid, and have an enamel surface to keep fiber from blooming. B-Lite poles are individually batch tested to 100kv per foot for 5 minutes. Mid section pole (also known as extension section) comes with a female ferrule on one end and male ferrule on the other.
