J-Cradle Kayak Carrier
Caution
• Tie down long or wide loads at the front and rear of the vehicle with non-elastic straps. If it looks like it can catch
some air, it will. TIE IT DOWN!
• When loading your surf gear or kayak, ensure that it is mounted correctly using the tie downs provided and is
positioned centrally, parallel to the vehicle.
• Check straps periodically during travel and tighten if necessary. Replace any straps that are worn or frayed before
using (see your Prorack dealer).
Important Warning
• It is critical that all Prorack racks and accessories be properly and securely attached to your vehicle. Improper
attachment could result in an automobile accident, and could cause serious bodily injury or death to you or to others.
• You are responsible for securing the racks and accessories to your car, checking the attachments prior to use, and
periodically inspecting the products for adjustment, wear, and damage. Therefore, you must read and understand all of
the instructions and cautions supplied with your Prorack product prior to installation or use.
• If you do not understand all of the instructions and cautions, or if you have no mechanical experience and are not
thoroughly familiar with the installation procedures, you should have the product installed by a professional installer
such as a boat carrier specialist.
