Right, that is from our old LO3000 line of products, which were tech-furniture/LAN-rack products. We have long since discontinued serving that market.
The LO3000 product line was picked up by Morrell Industries. It is still being sold: http://workstations.morrellindustries.c ... -furniture
. Not sure if they'd have the worksurface you want. And I am not sure if it would work with a WorkFit-D. Those LO3000 surfaces weighed a lot, so you might be reducing the lift capacity of your WF desk if you were to attach one.
I will say this: LO3000 was practically bomb-proof in its construction--you'll have that for a long, long time.
