Attaching the Extension Straps: For Larger/Taller Loads Connect/attach the Carabineer on the Cargo Safety Cover to the D-ring at the end of the Extension Strap. Attach the Carabineer at the opposite end of the Extension Strap to a secure tie down/anchor point. Follow the instructions on the Cargo Safety Cover to adjust height. For Smaller/Shorter Loads Connect/attach the Carabineer on the Cargo Safety Cover to the D-ring at the end of the Extension Strap. Grasp the D-ring in the center of the Extension Strap and connect it to the Carabineer on the Cargo Safety Cover (as in step 1). NOTE: This secures the strap and keeps the excess length from flapping around. Attach the Carabineer at the opposite end of the Extension Strap to a secure tie down/anchor point. Follow the instructions on the Cargo Safety Cover to adjust height. NOTES: For higher bed loads, four Extension Straps may be needed. Loads shift & settle; inspect after 10 miles; then every 40/50 miles thereafter (inspect in shorter intervals if on rough/bumpy roads or inclement weather). Make sure all connecting points on vehicle are secure. WARNING: Inspect product before each use. DO NOT USE: If product is deformed, worn, damaged, rusted or not securely installed.
