The Lockrack is designed to attach to most roof rack brands/styles, with an accessory groove.

Getting started:

  1. To attach the base plate, take the supplied flat screw and insert the plastic bush to the top.
  2. Insert the flat screw into the groove of your roof rack ensuring the bush stays above the roof rack and slide into the required position. Repeat this for the second flat screw.
  3. Next, take the aluminium base plate and peel the rubber padding off to reveal your attachment holes.
  4. Insert the bolts into the base plate and secure with the supplied fastening nuts until secure. A quarter drive socket wrench with 10 mm socket can be used.
  5. Next, re-insert the rubber padding to your base plate by simply pushing into place. You will know when it is seated properly when it clicks in and is flush with the base.
  6. You can now install your lockrack arms by simply releasing the locking pin by pulling, and sliding them into place until they click into position and are secure.
  7. Replace the rubber inserts on your roofrack (if equipped) once the Lockrack installation is complete.

The Standard Lockrack Bracket fits most Aero Bar Style roofracks that have a channel down the middle. This includes Yakima, Rhino, Prorack, Whispbar, Thule and Rola among others.

If your roof rack resembles the one pictured above the Standard Bracket will work. This type of bracket is supplied with the Lockracks.

If you have a Heavy Duty Lockrack (As pictured above), you will need the Heavy Duty Adaptors - Click here >>
If you have a Square bar style roof rack, as per above, then the Square bar adaptor is required. Click here >>
If you have an Aero Style bar, but it does not have the channel running down the middle, as per above, then you will need the Universal Adaptors. Click Here >>

If you have a Platform style rack on your vehicle, the Standard Bracket will work, however in some cases the Lockrack base may require a new hole to be drilled in order to line up with the bars. And in some cases the key may need to be trimmed slightly to ensure it can turn adequately.
