We are one of the leading manufacturers and exporters of Bolted Stirrup Clamps of Bronze and Stirrup Bail Clamps from Bronze from India. For over three decades, Conex Casting has been supplying premium-grade bronze overhead primary tap clamps to electrical utilities, power transmission companies, and infrastructure contractors worldwide across North America, Europe, Australia, the Middle East, and Asia. Our advanced foundry and machining capabilities allow us to produce bronze stirrup clamps that deliver exceptional conductivity, corrosion resistance, and long-term mechanical integrity for overhead power line tapping applications.
Our Bronze Bolted Stirrup Clamps and Bronze Stirrup Bail Clamps serve critical functions in electrical infrastructure — including overhead primary conductor tapping, ACSR conductor connections, AAC and AAAC conductor terminations, and permanent live-line tapping applications. We manufacture these clamps using high-grade Bronze Alloy (body), Copper-un-plated stirrups, and Bronze alloy or Stainless Steel eyestem, conforming to international standards and ensuring superior performance in high-voltage environments. Our product portfolio covers a comprehensive conductor range from #6 Sol–2/0 Str to 4/0–500 MCM, catering to a wide variety of utility and industrial requirements.
Bronze Bolted Stirrup Clamps & Stirrup Bail Clamps – Product Overview
Bolted Stirrup Clamps of Bronze are specially engineered for overhead primary tap applications in medium and high voltage power distribution networks. The eyestem is positioned at a 30° angle from the stirrup, allowing optimal conductor alignment and reducing mechanical stress at the connection point. Available in two eyestem material options — Bronze alloy or Stainless Steel — to suit coastal, industrial, and inland environments. A tin-plated copper loop variant is available upon request (add suffix “TB” to catalog number, e.g., CXB-S022019ETB). Clamps can be supplied factory-inhibited and bagged (add suffix “XB”).

Frequently Asked Questions – Bronze Stirrup Clamps
What is the difference between a Bolted Stirrup Clamp and a Stirrup Bail Clamp?
A Bolted Stirrup Clamp uses one or more bolts to mechanically secure the stirrup around the main conductor and the tap conductor, providing a high-force, vibration-resistant connection. A Stirrup Bail Clamp (also called a Stirrup Bail or Eyebolt Stirrup) incorporates a bail or eyestem as the connecting element, allowing a looped or eyebolt connection to a secondary line or service drop. Both types are manufactured by Conex Casting in Bronze for enhanced corrosion performance.
Are your Bronze Stirrup Clamps suitable for live-line installation?
Yes. Our Bronze Bolted Stirrup Clamps are designed for use in live-line hot-stick installation procedures commonly employed by electrical utilities for overhead primary tap connections. The factory-inhibited and bagged option (suffix “XB”) further facilitates safe, clean, and efficient live-line installation.
What conductor types are compatible with your Bronze Stirrup Clamps?
Our Bronze Stirrup Clamps are designed for copper conductors ranging from #6 Solid to 500 MCM, covering both stranded and solid formats. They are suitable for use with ACSR (Aluminium Conductor Steel Reinforced), AAC (All Aluminium Conductor), AAAC (All Aluminium Alloy Conductor), and bare copper overhead primary conductors.
Can I get Bronze Stirrup Clamps with custom catalog numbers or markings?
Yes. Conex Casting can supply bronze stirrup clamps with custom part numbers, utility-specific markings, or OEM branding upon request. Please contact our sales team with your specifications and we will provide a tailored quotation within 24 hours.
