It says “Availability: 1 in stock (can be backordered)”.

Can you confirm you have the item in stock as I don’t want to order it and wait for a long period of time to receive it as I need asap to replace my spindle that just died on me.

We are trying to order some 2080V aluminum extrusions. In addition to tapping, we need some special machining on the ends. How can we get a quote for this?

thanks,

Joy
