Front Runner Outfitters RRAC017 Rack Adaptor Plates For Thule Slotted Load Bars

The Front Runner Outfitters RRAC017 Rack Adaptor Plates are a purpose-built hardware solution that bridges the gap between Front Runner Slimline II Roof Racks and Thule slotted load bars. Whether you want to mount Thule Slotted Square or Aero Bars onto a Front Runner Slimline II rack, or mount a Front Runner Slimline II Roof Rack Tray onto existing Thule load bars, these adaptor plates make it possible — protecting your investment in both ecosystems.

Key Features:

• Mounts 2 Thule slotted load bars or Aero Bars to a Front Runner Slimline II Roof Rack
• Also functions in reverse — mounts a Front Runner Slimline II Roof Rack Tray to existing Thule slotted load bars
• Compatible with both Thule Slotted Square and Thule Aero load bar profiles
• Not compatible with Thule rectangular load bars that lack slots (the standard Thule load bar commonly sold in the USA)
• Constructed from 2.5mm (0.098 in.) 3CR12 high-strength steel with a durable black powder coat finish
• Attaches directly to Front Runner rack slats via the integrated T-slot mounting system
• Pre-cut fitment holes for precise, rattle-free installation
• All necessary hardware included — no sourcing additional bolts

Kit Includes:

• 4 x Thule load bar adaptor brackets
• Complete nuts and bolts kit (including T-slot bolts)
• Mountings for both Aero and Square bar profiles

Fabricated from corrosion-resistant powder-coated steel, the RRAC017 allows overlanders and outdoor enthusiasts to continue using their existing Thule accessories — such as bike mounts, kayak carriers, and cargo boxes — on a Front Runner Slimline II platform without replacing their gear.
