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.
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
General-purpose overhead stirrup tap connectors used in distribution networks for secure branch connections.
Manufactured with high-strength aluminum alloy bodies for excellent conductivity, corrosion resistance, and reduced weight.
Stirrup clamps featuring a U-shaped bail or loop, typically made from copper or bronze, allowing attachment of jumpers, hot line tools, or grounding leads.
Designed for overhead distribution tap connections
Suitable for AAC, AAAC, and ACSR conductors
Aluminum body for lightweight strength and corrosion resistance
Copper or bronze bail options for durability and compatibility
Dual eyebolts for balanced clamping and stability

Are stirrup clamps and hotline clamps the same?
They are closely related terms. Stirrup clamps designed for live-line installation are often referred to as hotline clamps.
Which conductors are supported?
Most stirrup clamps are designed for AAC, AAAC, and ACSR conductors. Selection is based on conductor diameter and size.
Do all stirrup clamps have two eyebolts?
Many standard designs use dual eyebolts for balanced clamping, though configurations may vary.
What material combinations are common?
A typical configuration includes an aluminum body with a copper or bronze bail.

Grounding and Bonding Clamps
Stirrup Clamps, Aluminum Stirrup Clamps, Hotline Clamps is a electrical connection component used in power distribution, grounding and cable termination. Final suitability depends on the approved specification and application conditions.
Typical applications include power distribution, grounding and cable termination. Confirm load, environment, mating parts and applicable standards before selection.
Specify conductive brass, copper, bronze or aluminium. State the exact grade because similar commercial alloys can differ in composition and performance.
Standard and custom sizes can be reviewed from conductor range, stud or thread size, contact area and mounting dimensions. Nominal size alone may not define compatibility.
Provide conductor range, stud or thread size, contact area and mounting dimensions, with units, tolerances and drawing revision.
Yes. Custom geometry, threads, tolerances and features can be assessed from a dimensioned drawing or approved sample.
Relevant Metric, BSP, BSPT, NPT, NPTF, PG, BA or BSW threads may be considered. Specify form, size, pitch, class and engagement length.
Options may include natural, tin-plated or nickel-plated. Specify coating type, thickness, appearance and corrosion or conductivity needs.
Tolerance depends on material, size, geometry and process. Mark critical dimensions and fits clearly on the drawing.
Check mating dimensions, orientation, sealing or retention method and specified tightening torque before use.
Inspection can cover material identity, critical dimensions, threads, finish and drawing-specific functional checks.
Material certificates, dimensional reports and coating or test records can be agreed at quotation stage.
Prototype or pre-production samples can be reviewed for new custom parts, subject to tooling and material requirements.
Minimum quantity and lead time vary with material, size, tooling, finish, inspection and order volume.
Provide the drawing or specification, material, dimensions, tolerances, finish, quantity, inspection, packing and destination.
