      Legal Considerations

      • The customer is fully responsible for careful installation into their vehicle. Use extreme caution. Do not drill into electronics, cabling and other OEM components below the dash surface! Research before any drilling!
      • It is not always possible to use this product or other mounting system depending on Federal, State and Municipality laws. Some States have strict rules on mounting devices that may, depending on poor positioning, impair a driver's ability to see the road. 
      • It is the responsibility of every customer - and not 67 Designs - to know the laws in their local area or in other regions if venturing from home. 
      • Research and know before purchasing any mount from 67 Designs.
      • 67 Designs is not responsible for any improper or illegal use of the hardware.
      • Patent pending.
