Step 2: Mock Up and Mark-Up

  • Place the feet on the roof about where you want them. Near the corners of the roof where it is strongest is probably best. 
  • Grab a few of the conduit clamps.  Lay one of the conduit cross-bars across the roof and set it on the feet. Hold on to it so it doesn't roll off.  The clamps will sort of clip on to the conduit by themselves.  Clip one on directly over the foot on whichever side of the vehicle you are standing.  This should keep it from rolling off while you move to the other side.  On the other side, clip on another clamp.
  • Adjust the position of the bar and the clamps until everything is sitting pretty much how you would like it when it is done.  Don't worry about the bars not resting flat on the feet if your roof is curved. We deal with that in the next step.
  • Using a marker, mark the positions of the clamps on the cross-bar and their positions over the feet.  This is just a starting point, before the clamps are tightened you can adjust their position along the bar.
  • If you think the bars will be wider than you need, now would be the best time to cut off the excess length from one side.
Looks like a Crown Vic. Just the roofrack that I need. I would add two more pieces of electrical conduit with four ninety degree angles and join the two cross pieces together.

Nice idea! I might try this.
Disclaimer: Dirt, sand, and other debris wedged between the foam or the blocks can scratch the car surfaces. <br /> <br />Disclaimer: Straps will cause damage to paint, plastic or glass. <br /> <br />Warning: Loading improperly can cause dents in the roof sheet metal. <br /> <br />1. Know your car rooftop weight limits. <br /> <br />2. Clean foam pool noodles, blocks, and roof surface to protect the finish from scratching. <br /> <br />3. Position blocks so the load weight is evenly distributed. Load your cargo so that it is evenly weighted side-to-side and front to back. <br /> <br />4. Loop strap firmly around your load to prevent side-to-side shifting. Run the strap through the doors of the car. Place ratchet strap inside the car. Tighten the strap and check the load often. <br /> <br />5. Attach front and rear straps to your load. Tie off your straps to the FRAME of the car. (Warning: plastic bumpers will not hold your load sufficiently) <br /> <br />6. Apply even pressure to front and rear straps <br /> <br />7. Failure to secure front and real of loads to the end of your car can result in property damage, personal injury or death. <br /> <br />8. Test the movement of the load before driving away. Rock the load side-to-side and front to back. Tighten again if loose. <br /> <br />9. Drive 5 miles and stop to check if all straps are still tight <br /> <br />10. Periodically check the straps for wear. Do not use the straps if faded or torn. <br /> <br /> <br />It is critical that this rack is 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. <br />
Excellent!! Great idea!
