Hastings, a worldwide manufacturer of hot-line tools and equipment, understands that every day has the potential to bring the unexpected to lineworkers. That is why Hastings designs every product – including our Super “U” Arm Extensions – with safety in mind.
The Super “U” Arm is designed with a profile “U” shape for greater strength and durability. The many features and benefits of the Super “U” Arm make it the best and most cost-effective extension arm available, according to Hastings. All arms include insulated conductor holders to ensure dielectric integrity.
Arms are rated for 34.5-kV phase-to-phase work applications. Arms with the standard conductor holder will accept conductors up to 1-1/16-inch O.D. or up to 800 MCM. Arms with the large-capacity conductor holder can accommodate a conductor inside a line hose. The gate latch on the large-capacity holder has an opening of 2 5/8 inches.
The Super “U” design is stronger than the traditional-style round extension arms. All Super “U” Arms and Super “U” Conductor Supports have a load limit of 200 pounds per wire holder. Interchangeable hanger loop kits are available for the different sizes of crossarms on your system.
