Shipping an 8.75 center

If you want it to get there in one piece...

1. Heavy wall or double wall cardboard box
2. Box should be 3 inches wider on all sides than the item inside
3. 3" ridged foam insulation on all 6 sides.
4. 1/8" plywood inside the cardboard box to reinforce the 6 sides
5. Bag the center section
6. Place center section on the box
7. Fill the box with popcorn packing
8. Tape the box with heavy duty filament tape. All 12 edges and around the middle in both directions.

It is heavy and the carrier WILL drop it many times.

I used to work in a department store shipping $100 to $300 (EACH and that's in 1980 dollars) crystal glasses to customers. I never had one of my packages come back broken.

Last note. A rectangular / square box will be cheaper than a round or irregular shaped box to ship. The weight is not as important. I shipped an empty box sized for an 8 3/4 housing ~12 lbs there ~75 bucks, ~50lbs back, ~85 bucks (actual numbers in my HOW TO SHIP an 8 3/4 HOUSING how to)

AND do not purchase the postage inside a UPS or FedEx store, you will pay retail vs the price online.
