Burndy KLU70 Copper Offset Tongue Mechanical Lug, 1-Hole

This Burndy copper offset tongue mechanical terminal lug is built for secure, dependable electrical terminations on grounding, bonding, and equipment connections. This 1-hole lug features a 1/4" stud size and an unplated copper finish, and it accepts a wide conductor range from #8 AWG solid to 2 AWG stranded copper wire. Sold under Burndy's SCRULUG™ trade name, this mechanical lug is a set-screw connector that delivers a fast, tool-only termination without the need for crimping equipment, making it a practical choice for electricians working in the field, in a panel shop, or on a service upgrade where reliable copper-to-copper contact is essential.

Key Features

  • Trade Size: 1/4" stud size fits standard grounding and bonding hardware for a secure, bolted connection.
  • Durable Copper Construction: Solid copper body provides high electrical conductivity and long-term connection reliability, even under repeated load cycling.
  • Offset Tongue Design: The offset tongue geometry improves clearance and alignment when terminating in tight enclosures or crowded panels, reducing installation time.
  • 1-Hole Configuration: Single-hole mounting pattern simplifies installation to grounding bars, equipment pads, and bonding points.
  • Wide Conductor Range: Accepts #8 AWG solid through 2 AWG stranded copper conductors, giving installers flexibility across a range of wire sizes on a single lug.
  • Mechanical Set-Screw Termination: The SCRULUG™ mechanical lug design allows quick, tool-only installation with a standard hex or slotted driver, eliminating the need for a dedicated crimping tool.
  • Unplated Finish: Bare copper finish is suited for standard indoor electrical terminations.

Technical Specifications

  • Conductor Range: 8-2-AWG
  • Trade Name: SCRULUG™

Typical Applications

  • Grounding and Bonding Connections
  • Panelboard and Switchgear Wiring

Burndy KLU70 – Frequently Asked Questions

1) What wire sizes does the Burndy KLU70 lug accept?
The KLU70 takes copper conductors from #8 AWG solid up to 2 AWG stranded, so one lug covers a branch-circuit ground wire and a service-size bonding jumper alike. It's a set-screw (mechanical) termination, so the same body handles anything in that range without changing dies or tooling.
2) Will the KLU70 bolt to a 1/4 inch ground bar stud?
Yes. The KLU70 has a single mounting hole sized for a 1/4 inch stud, which is the common stud on grounding bars, equipment bonding pads, and panelboard ground bars. One hole means you should snug it against a flat, clean pad so the tongue can't rotate under torque.
3) Do I need a crimper to install this Burndy lug?
No crimper. The KLU70 is a SCRULUG mechanical lug, terminated with a set screw using a standard hex or slotted driver. That's why panel shops and service crews keep them around: no dies, no hydraulic head, and the connection can be backed out and re-used if a conductor has to be re-pulled.
4) Can I use the KLU70 on aluminum conductors?
No. The KLU70 is a copper body in a bare, unplated finish and is specified for copper conductors from #8 solid to 2 AWG stranded. For aluminum or for mixed aluminum/copper runs you need a lug marked AL9CU or equivalent dual-rated, typically plated. Putting aluminum into a copper-only lug risks a galvanic, high-resistance joint.
5) What does the offset tongue on the KLU70 actually do for me?
The tongue is stepped off the barrel axis, so the bolt pad sits on a different plane than the conductor. In a crowded panel or a shallow enclosure that buys you clearance and lets the wire approach the ground bar without a hard bend. If your conductor lines up straight onto the pad, a straight-tongue lug is the simpler pick; the offset earns its place when the bar and the wire are not on the same plane.
6) Is a bare copper lug OK outdoors or in a wet location?
The KLU70's finish is unplated bare copper, which the spec calls out for standard indoor electrical terminations. Outdoors, in damp vaults, or in corrosive/marine air, bare copper will oxidize at the joint. For those spots pick a tin-plated lug, or at minimum treat the connection with a listed oxide-inhibiting joint compound inside a suitable enclosure.
7) Is one KLU70 enough for a ground bar connection, or do I need a two-hole lug?
For most grounding and bonding terminations on a bar or equipment pad, the single 1/4 inch hole is what's used. Where a spec or drawing calls for a two-hole NEMA pad, typically on larger feeder and switchgear terminations where rotation has to be positively prevented, the KLU70's 1-hole pattern won't satisfy it and you need a 2-hole lug instead.
8) What is the Burndy part number to order and where do I get the spec sheet?
Order it as Burndy KLU70, the manufacturer part number. Burndy publishes the spec sheet for it directly, at hubbellcdn.com/specsheet/BRDY-KLU70-SPEC-EN.pdf, which is the document to attach when a submittal package asks for the lug cut sheet.
9) Can I standardize on the KLU70 across a building's panelboards?
It's a reasonable standardization item for indoor copper grounding and bonding work: one part number covers #8 solid through 2 AWG stranded, mounts to a 1/4 inch stud, and installs with a driver instead of a crimp tool, so stockroom and truck inventory stays small. The limits to plan around are copper-only conductors and indoor, dry locations.
