Product Details

The Install Bay SB4 is a 4 gauge snap bushing designed to protect electrical wiring where it passes through metal panels, firewalls, and chassis. By converting raw-edged holes into smooth, insulated openings, these bushings prevent chafing and abrasion damage to wire insulation — a critical step in any clean, professional-grade 12-volt installation.

Key Features:

  • Wire Gauge: 4 AWG
  • Inner Diameter: 0.402 inches
  • Outer Diameter: 0.595 inches
  • Snaps securely into pre-drilled holes — no tools required
  • Locking fingers grip the panel to prevent pull-out
  • Insulates and mechanically protects electrical connections, power cables, and utility lines
  • Made from durable black Nylon 6/6 material
  • Ideal for car audio amplifier wiring, battery cable runs, and general automotive electrical installs

The SB4 snap bushing is an essential hardware item for car stereo installers, fabricators, and DIY enthusiasts routing 4 gauge power wire through sheet metal. Sold individually — also available in a 100-piece bag (MPN: SB4US).
