SAFETY PRECAUTIONS
WARNING: Due to the variety in the design of vehicles and roof bars/racks, it is the
user’s responsibility to ensure the ladder rack clamps are fitted and attached
correctly.
DO NOT use the ladder rack clamps if any parts are damaged or missing, as this may
cause failure and/or possible personal injury.
ALWAYS maintain the ladder rack clamps in good condition.
Replace or repair damaged parts. Use genuine parts only. Unauthorised parts may be
dangerous and will invalidate the warranty
ALWAYS familiarise yourself with the applications and limitations of the ladder rack
clamps, as well as all potential hazards.
DO NOT use the clamps for any purpose other than that for which they are designed.
ALWAYS use the ladder rack clamps in pairs. One at the front and one at the rear.
During use frequently check that the ladder rack clamps and ladder are secure.
DO NOT over tighten the ladder rack clamps. This may cause damage to the roof
bar/rack or the clamps.
Only use this product to clamp ladders.
Remove any loose objects from the ladder prior to clamping to the roof bar/rack.
WARNING! Ensure that neither the ladder rack clamps or the ladder project beyond
the maximum profile of the vehicle.
WARNING! When a ladder is clamped to the roof bars/rack, the characteristics of
the vehicle will change. Driving techniques should be altered to allow for this. Reduce
speeds and allow longer braking distances.
ALWAYS check that the ladder is secure and stable prior to transit.
WARNING! The security and safety of the load carried is the responsibility of the
vehicle driver.
WARNING! The warnings, cautions and instructions in this manual cannot cover all
possible conditions and situations that may occur. It must be understood by the
