Hey FM,
Sorry for not replying until now but I was traveling all weekend.
Here is information that should answer your questions:
1. Futura slides are available in 9", 12" 15" 18" and 21".
2. We have 2 versions. One is for 1/2" or 5/8" drawer material and the second is for 3/4" drawer material
A7555 - For 1/2" or 5/8"
A7955 - For 3/4" drawers
The drawer width calculation is the same as the Tandem however please note that the Futura slide rides 4mm (3/16"). For the most part, this only affects the placement of the drawer front. (It will drop down 4mm).
For the product number here are the codes. Name: "Futura"
A7555/381 -15"
A7555/457 - 18"
A7555/533 - 21"
Let me comment on this slide shortage. This has been caused indirectly by COVID. As a result, steel is in short supply for everyone. Salice, like Blum finds this challenging. In addition to steel, transportation is another contributing factor. Due to COVID restrictions in Europe, container boats are locked down in many ports. Here in the states, containers are stuck in port and can not be un loaded to to labor shortage. Finally, trucking companies are also hurt by the labor shortage and other restrictions preventing movement from state to state. As you can see the entire supply chain has been paralyzed. Salice has faired better than most in that many sea ports throughout the country where Germany and Austria are land locked.
In spite of our flexibility, our inventories may not be sufficient to accept orders far above our normal inventory levels. We will do our best.
All I can say is to contact your Salice distributor ( Richelieu and many more) to check their inventory status.
Here is a schematic for the installation and the link to our web site for full details.
Best of luck, we are all in the same boat rowing upstream.
Regards,
Dennis
