Have a Dek-It mount I bought and ended up not using. Brand new, never had a screw in it. It's the 22.5 version that has a little angle on it to set graph back off top of tray a little. Also have an extra 15 foot extension Ethernet cable I did not need. Brand new also.
SOLD shipped for the Dek-It
$45.00 shipped for the Ethernet.
