Treefrog has switched to a new, lighter and more flexible color matched wood backer to make Treefrog even better. It’s still the same great veneer face. We’ve changed our SKUs, for example, #60204 is now #40204. The only thing that changes is the first #. We still have inventory of most “old” Treefrog SKUs, but they are being replaced by “new” SKUs. Click on the link “Formerly #6XXXX” atop each new SKU page to see the old version. Contact us or your Treefrog distributor to check inventory levels of any Treefrog SKU. We have material in stock in USA.
