At a glance

  • 270 lbs Breaking strength
  • 0.85 mm (Flat) Diameter profile
  • Flat clearance braid Braid geometry

Field-use notes

  • Tight clearance fitment: Deploy the SF 301 series for custom vehicles, aftermarket windshields with thin gaps, or quarter-glass replacements with low body-line clearances.
  • Warranty warning: Use of braided steel wire in WRD devices voids all manufacturer warranties and causes severe guide housing wear.
  • Suction setup: Route the flat line close to the glass using the Install Stick (WRD-IS) notch to keep it aligned within the pinchweld track.

Field advantages

Flat low-clearance braid

Lays flat against the pinchweld channel, enabling horizontal sliding in tight tolerance gaps where round lines bind.

Good molding salvage

Designed to glide beneath weatherstripping and decorative molds without lifting, shredding, or damaging them.

Reduced friction profile

Laying flat distributes the shear force, reducing localized friction heat and avoiding Ceramic Frit scoring.
