Product Information:
Add the Multi-Seam Expansion Kit to join and level TWO seams at the same time (up to 14 feet apart), or "chain link" all 4 seam setters together for one large seam.
-storage case (grey tool box style)
-2 seam setters (same as in the VCA kit)
-one 12' Tube Adapter

Now you can:
1) Set a longer seams (i.e. island seam) by attaching either 1 or 2 of the additional seam setter units in the series (doesn?t require the coil tube for this, each seam setter already has an air tube that can connect to other units when they are in close proximity), or
2) Set one seam on one side of the kitchen, and a separate seam on the other side of the kitchen while using only one pump (the coil tube connects both sets of seam setters).
