BL (Lightweight) Hollow Core Fiberglass Saw Head Poles are commonly used in the tree care and landscaping industry for general pruning. B-Lite fiberglass poles are super lightweight, very strong, rigid, and have an enamel surface to keep fiber from blooming. The base pole has a rubber end cap and female ferrule and are individually batch to 100kv per foot for 5 minutes. For highest performance and safety, Jameson recommends using a base pole when using one pole or starting with a base pole when working with multiple poles.
