Step 1 - Check
Make sure you have all the hardware required for each bracket.
OZ11/OZ15/OZ20 Installation Instructions - Ozroofracks
For full installation instructions follow the manual that came with your set or download it below. It's especially important to refer to your vehicle manual in order to know the loading rate of your vehicle roof. Remember that the condition of your gutter and the weight of the accessories clamped will affect the stability of this product.
IMPORTANT: Power tools are NOT REQUIRED to install our product/s. By using power tools you can damage your vehicle and the thread on the brackets. If you need to specifically tighten up a bracket, use the lock nut provided behind the bracket nut (for extra safety). As any other metal autopart some parts are masked when powder coating (like the threads) meaning bare metal is expose. If you're planning a low-maintenance and/or long-lasting installation use a good silicone self-fusing tape, liquid sealant, high density thread seal tape or anaerobic sealant to avoid rust.
Step 2 - Clean
Clean the gutter and make sure there is nothing where you'll place the bracket.
Step 3 - Protect gutter
Place a piece of paper on the vehicle wall to protect it from scratches.
Step 4 - Gutter Plate
Put the gutter small plate over the gutter, laying down over the vehicle wall.
Step 5 - Put the rubber
Fit the adhesive rubber on the bracket, where the bracket will contact the vehicle (under gutter - fig.3).
Step 6 - Position
Gently position the bracket under the gutter, securing the over gutter plate.
Step 7 - Start tightening
Now you can start tightening the bolt to the bracket, be careful as depending on the bolt used it might stick close the van wall.
Step 8 - LOCK
Once you see the bolt thread from the back, place the thin safety lock nut. Not just especially helpful on rough roads but proofed to increase x3 times the downwards strength of the bracket.
Step 9 - Finish
Everything should be ready by now to fit accessories and re-check the installation.
Step 10 - Prevent Damage
Check often your installation and make sure that any accessory fitted to the bracket is at least 3-5mm away from the vehicle.
Step 11 - Preventive Treatments
We encourage installers to use a good silicone self-fusing tape, liquid sealant, high density thread seal tape or anaerobic sealant if you're planning a low-maintenance and long-lasting installation.
