T R A N S MI SS I ON - CPI www.hubbell.com/cpi | J-31 Bolted Wedge Stirrups - Aluminum CPI™ Shear Bolt Wedge Stirrups, Aluminum Accommodates 226.8 ACSR 30/7 - 1272 AAC CPI Aluminum Stirrup Connectors are designed for connecting to aluminum or copper conductors. Stirrups are intended to protect the main line conductor from damage and arcing as hot line clamps are connected and disconnected. During installation, when proper spring tension and torque is achieved, the shear head bolt will break off giving the install a positive indication of a corrected completed connection. Features and Benefits • Easy to remove and re-use without damaging the conductor • Heavy duty tin plated bail has a large loop to allow for multiple connection positions while also eliminating galvanic reaction • Easy to install with standard socket or impact wrench, requires no special tools • Easy adaptable to standard hot stick tools • High-conductivity grit corrosion inhibitor is factory applied for ease of installation and longevity while the connector is in service • Remains permanently locked through fault current or power surges • May be used in non-corrosive environments to connect copper conductors • Excellent option for emergency restoration where outside crews might not have shoot-on or compression tooling Clip & Wedge Interface (Alum) Shear Bolt (Alum) Bail (Tin-Plated ) Copper 4.5” 5.0” “C” Body (Alum) Catalog Number Conductor Main Main Dia.
