Beveled timber

Yes it works better than regular dunnage. U can buy the coil racks that u put regular dunnage in and it tilts them to a 45 degree angle. Thats what i used. Some places wont load u with regular boards because it can damage the coil

 

I got 6 of them and only used them once . So i cant speak to the durability of them but they weigh a good 20 pounds each. Very heavy duty and they worked well. Would definatly recommend if you dont haul coils to often and dont wanna carry beveled lumber

 

If memory serves me, TMC uses them exclusively.
Seem to be stoutly built.

 

Yes

 

I've been using this style for the past year or so. I don't have any issue with the racks themselves but find the wood doesn't last as long as bevelled wood sitting on the floor in conventional racks. They are more compact for storage though.

 

If square 4x4’s is all you have, it’s a good idea to lay some felt pads on the cornered edge of the boards.

 

Can I ask what kind of wood you're using?

I ask cause I've got about 3 years in the angled racks using the exact same unbeveled timbers. Probably close to at minimum using the wood 2 x a week and it was always just on top of one of my side-boxes exposed to the weather too...

Im using true oak 3.5x3.5"

Had to grab some beveled and racks for my brother the other day at tarp stop (only had 3 angled racks and they seem poorly built compared to my 6 year old ones) and there was a ton of soft poplar, a completely split peice of ash, I had to really dig to come up with hardwood
