Hotline clamps, Stirrup clamps , Aluminum Stirrup Clamps, Hotline clamps, Aluminum Stirrup Bail Clamps, bronze hotline clamps

Stirrup Clamps, also commonly known as Aluminum Stirrup Clamps, Hotline Clamps, or Aluminum Stirrup Bail Clamps, are heavy-duty mechanical connectors used for making tap or branch connections on overhead distribution conductors. These clamps are widely used by utilities for both energized (hot line) and de-energized installations on AAC, AAAC, and ACSR conductors.

Designed for strength, reliability, and ease of installation, stirrup clamps provide a secure mechanical and electrical connection while allowing repeated installation and removal during line maintenance.

What is a Stirrup Clamp (Hotline Clamp)?

A stirrup clamp is an overhead tap connector that clamps onto a main conductor and provides a bail or loop for connecting a tap conductor, jumper, or hot line accessory. Because many designs allow installation using hotsticks, these connectors are frequently referred to as hotline clamps or hot line stirrup clamps.

They are commonly specified where utilities require:

Frequent connection and disconnection
Live-line (energized) maintenance
Strong mechanical holding with reliable electrical contact

Product Range

Stirrup Clamps

General-purpose overhead stirrup tap connectors used in distribution networks for secure branch connections.
