I sure wouldn't move that granite on a roof rack. Generally, those sorts of granite pieces are shipped on edge because the material won't stand up to any sort of flexing across the flat dimension.

All you need is to hit a pothole, flex that tabletop and have it shatter on top of your car, scattering pieces of granite along the highway.

How much was the dinette set and is it of sentimental value? I suspect the most prudent solution that is not destined to fail, would be to sell the one in NJ and buy a new dinette set in Tejas

Generic granite weighs 6lbs per sq. ft./per centimeter thickness.

Granite is rarely 1" but is possible; is usually either 2cm or 3cm (~3/4" or 1 1/4").

Based on 9.6 sq. ft. it would weigh:
2cm = 115lbs
3cm = 173lbs

My concern would be for the DYNAMIC forces at work...not just the under 180# weight of the granite slab.

Think

p = mv

which measures the momentum of a moving object

Without actually coming up with numbers, consider the momentum of a 180 lb. granite table strapped to a Sentra at highway speeds when suddenly, you have to brake hard or make an extremely evasive maneuver!! You now have a dangerously heavy granite Frisbee launched from the top of your car!

I had my old VW loaded with about 40 lbs of apartment stuff on a roof rack clamped down overhead. I had to brake hard at one point, and the ENTIRE rack, contents and all ejected several feet in front of the car!! That was scary! Can't imagine how a granite table would fare in the same situation...

Transporting flat it should be supported by a sheet of 3/4" plywood approx the same size as the top to reduce flex. You dont want padding between the two. Four 3" C-clamps will hold it down to the ply; attaching that structure to the rack safely is obviously an important consideration as is attaching the rack to the car.

FWIW, there are numerous Chinese importers selling very cheap prefab stone countertops who also bring in prefab furniture tops. Might be cheaper and easier in the long run to bring the frame home and just buy one locally.

It's not sentimental. It's just size & color wise, it fits our place perfectly. Just throwing it out there.

X2. Leo has it right. Resting horizontally, it WILL crack, nevermind the weight.

If anything, find someone with a van and ask them to transport it. Wrap it well and store on its edge for travel.
