The pivot pole length adjusts as you build up igloo block layers. The tool helps you easily and reliably make a complete and habitable igloo dome for winter/snow camping, or backyard fun. To use the ICEBOX® Igloo Tool, set the tool in place with the clamps on the tool form. Fill the tool form with snow.

Pack the snow in the form as it is shoveled in. This will also help to mold and attach the new igloo block to the previous layer and the adjacent igloo block. After you have completely filled and packed the ICEBOX® Igloo Tool, unclamp it, slide it to the next position and repeat the process while adjusting the pole 1 adjustment per layer.

Your kit will include a pole with 8 adjustments, 1 for each igloo block height layer. The pole length adjusts while you build your igloo to ensure the correct domed catenary shape. The pole is also key to support the weight of the snow and form while packing the snow.

After finishing 6 rows of the igloo you remove the outside of the form as the wall is now leaning in far enough so the snow can be packed from the outside.

The snow only needs to hold its form well enough to stay in place until you start the next block. 8 total rows are built including the final cap.
