Copper Tape Connector – Brass Square Four-Way Junction Clamp

The Copper Tape Connector is a heavy-duty brass square junction clamp designed for joining, crossing, and directing flat copper earth tape in earthing, bonding, and lightning protection systems. As seen in the product image, it features a solid square brass body secured by four brass screws at each corner, with four open slots — one on each side — that accept flat copper earth tape running in any direction.

Four-way earth clamp connectors of this type are used with copper earth tapes to achieve cross, straight-through, or tee joints in flat tape. The clamp base has a countersunk hole in the middle for securing the clamp to a building surface, and the lid is fixed by means of four screws. Power and Cables

How It Works

The connector consists of two brass plates — a base and a lid — that sandwich the copper tape tightly between them when the four corner screws are tightened. The tape is inserted into the appropriate slots before the lid is fastened down. The clamping pressure of the screws creates a firm, low-resistance mechanical and electrical bond between the tape conductors at the joint. No soldering, brazing, or special tooling is required for installation.

Brass Square Tape Clamps, Bronze Square Tape Clamps, and Copper Tape Clips are used for the interconnection of multiple copper earthing tape conductors or for changes of direction, ensuring a low-resistance, highly corrosion-resistant connection. They are used for forming straight-through, cross, or tee joints in earthing tape. Copperearthingaccessories

Key Features

Solid Brass Construction — Brass provides excellent electrical conductivity, strong resistance to corrosion, oxidation, and environmental degradation, as well as robust mechanical strength — ensuring long-lasting, reliable grounding connections. Copperearthingaccessories

Four-Way Connectivity — The four open slots accommodate tape entering from all four cardinal directions simultaneously, making it ideal for grid-pattern earth tape layouts common in substation and building earthing systems.

Screw-Clamp Mechanism — Four brass screws pull the lid firmly onto the base, compressing the tape conductors between the two faces for a secure, vibration-resistant connection that maintains conductivity over time without re-tightening.

Surface-Mountable — The countersunk central hole in the base allows the clamp to be bolted or screwed directly to concrete, masonry, steel structures, or cable trench frames, keeping the earthing conductor firmly in place.

Versatile Joint Configurations — A single connector can serve as a cross joint (all four tape entries used), a straight-through joint (two opposite entries), or a tee joint (three entries) — eliminating the need for multiple connector types on a single installation.

Applications

This connector is used wherever flat copper earth tape must be joined, branched, or redirected within an earthing or lightning protection network. Typical installation environments include:

  • Electrical substation earthing grids and perimeter electrode systems
  • Building and structural earthing systems per IEC 62305 and BS 7430
  • Lightning Protection System (LPS) down conductor networks and ring conductors
  • HV/LV switchgear panels, switchrooms, and distribution boards
  • Cable trench earthing along trench edges and metallic trench covers
  • Industrial plant earthing and equipment bonding systems
