FAT IVAN® - Fold Up Door Stopper 

The World’s Only Fold-Up Door Stopper is a heavy-duty door stopper designed initially by a firefighter for emergency services. However, Fat Ivan® proves vital for many fields, including Fire, Police, Commercial, Residential, Hotel/Motel, and all deliveries. The easy one-handed operation opens quickly for insertion and never slips off the hinge, guaranteed. Just place Fat Ivan® on any hinge, top, middle, or bottom; then let it go and walk right through. FatIvan® folds up quickly and stores in any space. You can also attach it to any metal surface with the embedded magnets.
