I got this email from Blum, it was a very big surprise that they don't sell bottoms and back parts.

Where can I buy mental bottoms and back parts?

Hi Anna,

For the SPACE TOWER, you will need to buy 1- M series LEGRABOX, and 4- C series LEGRABOX. You will need to pick your V1 package based on length and series. That is on pg. 12-17 of the catalogue, make sure you pay attention to the header to ensure you get the correct color you want.

For the interior rollouts:

M Height (pg. 38-41): You will need to purchase box numbers 3 + 5 on pg. 39.

C Height (pg. 46-49): You will need to purchase box numbers 3, 4, and 5 on pg. 47.

I have attached some literature about the SPACE TOWER and the pages you need to reference in the LEGRABXO brochure.

The bottoms and backs of the drawer will have to be made by the cabinet maker.

Best regards,
