• Slide t-nuts into the rail channel and press them tight against the metal.
  
• The wide rim spreads load evenly to protect soft aluminum surfaces.
  
• Keeping handy backup bolts saves time during quick equipment swaps.
  
• Tighten every joint firmly to stop shaky gear from wobbling your setup.
