High quality clip on net. If your table is not a full time fixture in your basement, then this will be a better net for you then any of the 'screw-clamp' based nets.
The strong clip on this keeps the net very secure and protects your table with thick rubber jaws. The net post itself folds down flat and is height adjustable with the knob on the bottom.
In the photo inset, you can see the net tensioning system. You put the string in a hole in the rod and turn the knob until the net is the tension you want. This system produces an extremely tight net, better than most ball-chain systems.
