Stud Flag Locking

These cast copper lugs are perfect for heavy duty usage. The different choices can be stacked, locked, crimped, and/or soldered.

The Only Battery Connectors That Exceed SAE Standards, are UL/CSA Listed AND Made in North America.

Quick lugs are precision die cast connectors made with a special copper alloy, tin plated for added conductivity and corrosion resistance. Permanent, indelible, readable gauge and polarity are stamped on each lug. Quick Connectors are listed by UL (UL STD 486A) and CUL when applied with Quick Cable Quick Crimp tools 4255, 4255M, 4255R, and 4255MR (standard and ratchet versions). Kits are available.

These heavy-duty cast copper flag connectors feature the same locking friction ridges to hold connectors in place. You can stack them and mix cable gauges.

  • Use with stud batteries, enables multiple battery hook up
  • Stackable, 24-position anti-rotation teeth bite into lead for positive hold
  • Connectors of different cable gauges can be mixed for maximum application and layout flexibility
