Burndy SCRULUG Offset Tongue Copper Terminal Lug, 1-Hole Mechanical Connector

The Burndy SCRULUG offset tongue copper terminal lug family is engineered for dependable mechanical wire termination in commercial and industrial electrical systems. This mechanical lug line is available in conductor sizes ranging from #10 AWG Stranded Copper up through 4/0 AWG Copper and 350 kcmil Copper, giving installers a matched lug for a wide span of feeder and grounding conductor sizes. Every option in the family shares a 1-hole mounting pad, an offset tongue geometry, and solid, unplated copper construction, making the SCRULUG line a consistent choice for bolted connections to bus bars, ground bars, and equipment terminals.

Key Features

  • Conductor Size Range: Available across #10 AWG Stranded Copper, 4/0 AWG Copper, and 350 kcmil Copper conductor sizes so contractors can select the correct lug for the application.
  • 1-Hole Mounting Pad: A single-hole pad on every size provides a secure, code-compliant bolted connection point to bus bars, ground bars, and equipment terminals.
  • Offset Tongue Geometry: The offset tongue design allows multiple lugs to be stacked or positioned closely together on a common bus bar or terminal pad, saving valuable space inside panels and enclosures.
  • Solid Copper Construction: Every size in the family is machined from solid copper for high electrical conductivity and reliable long-term mechanical and electrical performance.
  • Unplated Finish: A bare, unplated copper finish is suited for standard indoor termination applications.
  • Mechanical Terminal Lug: Part of Burndy's SCRULUG™ series of mechanical terminal lugs, designed for straightforward field installation without special crimping tools.
  • Stud-Matched Hardware Fit: Each conductor size is paired with a correctly sized mounting hole for a consistent, vibration-resistant bolted termination.

Why Burndy?

Burndy is a long-established name in mechanical and compression electrical connectors, and the SCRULUG™ offset tongue lug family reflects that focus with solid copper construction, a 1-hole mounting design, and a conductor size range spanning #10 AWG Stranded Copper through 350 kcmil Copper that simplifies selection for electrical contractors and panel builders. This offset tongue terminal lug line is built for the kind of secure, code-compliant wire terminations that commercial and industrial electricians rely on for grounding, bonding, and power distribution work.

Burndy KLU25 – Frequently Asked Questions

1) What wire size does the Burndy KLU25 terminal lug accept?
The KLU25 is a range-taking lug that accepts #14-10 AWG solid copper conductors, so one part covers several gauges instead of stocking a separate lug per wire size. That range applies to the KLU25 specifically, not to the other models in the KLU line.
2) What bolt or stud size does the Burndy KLU25 lug mount to?
One mounting hole, sized for a #6 stud. That matches it to #6 studs on bus bars, ground bars, and equipment terminal pads. If your pad is drilled and tapped for a 1/4-20 or larger stud, the KLU25 pad is not the right hole size.
3) Can I use the Burndy KLU25 on aluminum conductors?
No. The KLU25 is specified for solid copper conductors, #14-10 AWG. For aluminum or dual-rated AL/CU work you need a lug rated for that conductor material, not this one.
4) Why choose an offset tongue lug instead of a straight tongue one?
The offset tongue steps the pad away from the wire barrel, which lets you land several lugs side by side or stacked on a common bus bar without the barrels colliding. In a tight panelboard or enclosure that is usually the difference between the terminations fitting and not. A straight tongue is fine where you have clear space around the pad.
5) Is the Burndy KLU25 lug plated or bare copper?
Bare, unplated copper. The body is machined solid copper for conductivity, and the unplated finish is intended for standard indoor terminations. For wet, corrosive, or outdoor locations, look for a tin-plated lug instead.
6) Is the Burndy KLU25 a mechanical set-screw lug or a crimp lug?
Mechanical. It belongs to Burndy's SCRULUG family of mechanical terminal lugs, so the conductor is secured with a screw and no compression tool or die set is needed. That is the practical reason contractors pick it for field and retrofit work over a compression barrel.
7) What other models are sold alongside the Burndy KLU25?
Three models are offered: KLU25, KLU225, and KLU300. They are the same SCRULUG mechanical offset tongue family; order by the exact model number, since the wire range and pad hole differ between them.
8) Is the Burndy KLU25 suitable for equipment grounding and bonding?
Yes, grounding and bonding is one of its stated uses, along with panelboard and switchgear terminations and motor control center wiring. The bolted #6 stud pad gives you a fixed, vibration-resistant connection to a ground bar rather than a pressure-only joint.
