Don,

I do not know if Linak sells direct to the general public.  Here is a link to their website:

https://www.linak-us.com/products/lifting-columns/

The DL2 is the column that I have been using.

If you have access to a machine shop that can fabricate top and bottom plates for the columns, the completed lifting column setup can be cheaper than a system from Pier-tech.  But if you do not have the resources to fabricate the needed plates, then it is probably best to pay more and get a system from Pier-tech.  My next door neighbor runs a small machine shop and another friend is a welder, so I had access to the resources I neede to make a system once I purchased the lifting columns, control box, hand controller and cables.
