Remember to place a distance of about 3 to 3 foot in between.
How to tie lumber to roof rack.
My car with roof rack with cross bars installed.
Then secure the front and back ends of each lumber bundle with ratchet straps to prevent movement photo 1.
The second option is the side racks.
Oh and remember to prepare two other pieces of wood for later use.
Ideally you ll have some kind of roof racks to tie things onto.
Nylon rope also works but be prepared to tie some trucker s knots.
Don t know if i d carry much lumber on that short front to back rack but i would definitely use at least two good ratchet straps ratcheted very tight around the lumber bundle so nothing could slip out.
With the third option crossbars with side rails you can secure an item to the side rails and run tie downs from front to back securing them to the crossbars.
Load your sheet of plywood on the roof rack.
These are great for a lot of reasons but mostly because they give you something solid to anchor to so that your roof mounted load.
Place 2 pieces of wood about 8 foot long on the roof rack on the lengthwise.
I use 4 hand clamps at the corners to hold the plywood to the 2 x 4 s.
Plus the tiedown to the trailer hitch.
Start by loading dimensional lumber onto the rack with the narrow edges resting on the crossbars.
For plywood i put two 2 x 4 s on the roof rack and place the plywood on top of those to stiffen the plywood otherwise it flops up and down at highway speeds.
That prevents the bundle from sliding forward backward or side to side.
On each side of the roof you ll see a rack that runs the length of the roof of the vehicle.
Use a tie down that wraps around the item and the rails.
Ask for help from friends if the sheet is too.
Assess your rack situation.
There are really three kinds of scenarios for your roof wood said.
Next secure the load to the rack using ratchet straps photo 2.
My car with 4 x8 mdf board on the roof rack.
4 web ratchet straps in a pair of x formations to hold down the board to the cross bars.
Wood also advises against bungie cords as they re too prone to flex when driving at speed and causing loads to shift and possibly escape.
Then i use the nylon web tie downs i ve got in the photos of below.
That s in addition to then attaching the bundle securely to the rack.
