Modular Fiberglass Igloos

 

The interior bolt together flanges extend into the igloo 4 inches. They are very strong and therefore objects can be fastened to them and supported by the flanges.

 

 

Holes can be drilled through them to run conduit or 1/2" H2O pipe if desired. If the igloo is has foam insulation, the foam would typically only come out the 4 inches max.

The bolt down tabs are to fasten the igloo to concrete pads or to install long stakes in the ground to anchor the igloo in it's location against hurricane type winds.
