I'm glad to hear back from someone. I'm planning a trip to China in 3-weeks and perhaps if it looks like we could do business I'll stop and visit.
Looks like you make what we are using in our trailer manufacturing business. We are starting to export other items from China and want to explore these as well.
Please see the attached pictures.
#0207: Type #42 square 2" matches up with hub, 6 bolt on 5.5" 3000 lb. /
#0223 2" X 10" brakes, drum and spindle #84 posi-lube 1750 lb. Bolt pattern 5 on 4.5"
#0222 shows distance from brake plate to end of shaft on the1750#
We are also using a 2" coupler and a 15" side crank jack, 2000#
These are typical American standard sizes.
What do you think. If you have please tell me who else in USA that uses your product. We want only good quality products to form a lasting relationship with you. Please quote pricing and what port.

Thank you,
Steven
