連接器（黑色）

I used these to link my 600 and 800 side by side and the fit is rock solid, no wobble at all. The elastomer pads underneath really do keep everything from sliding around on my counter.

These connectors snapped onto my 700 units perfectly and the elastomer pads really do keep everything from sliding on my tile floor. Aluminum feels solid, not flimsy like the plastic ones I had before. Four in the set was exactly what I needed for my setup.

I was worried the feet would slide around on my hardwood, but the elastomer pads grip really well. The aluminum feels solid and the four extenders lock my two units together with no wobble at all.
