Let me jump in regarding the email below. I think the price difference was due to the rounding up of the numbers in the spreadsheet. I am still on the road in Melbourne and I will check and come back to you when I get back to Bangkok on Tuesday.
Regarding the KBR160EC, I understand that you wanted to order the Joint Adaptor to able to turn the End Cap into a Corner Joint. Can you let us know if there is a preference if you need the Left or Right handed versions of the End Caps since the end caps will be supplied assembled. We can do a combination of Left and Right handed versions to make up the MOQ.
Also how many of the Joint Adaptors you will need in addition to the KBR160EC so that you can make up the Corner Joints.
I will send you the drawings of the new aluminium bases with the LED cavities when I get back.
