The Stuff Stopper Under-Fridge Bumper
The Stuff Stopper stops dropped fish eyes, spilt civet poop coffee beans, and that edible dehydrated zebra tarantula that wasn't quite fully dehydrated from scurrying into the abyss beneath your fridge. Install the extendable rod at the base of your appliances and it will catch grapes, Skittles, craft beads, and your kid's toy car from rolling out of recovery range too.
The Stuff Stopper serves as a bumper for your refrigerator, oven, washer, and dryer. It slips under the appliance (at least 1/4" of clearance to the floor is needed) and expands from 23" to 37" long to cover the gap's full span. The arms at the end of the Stuff Stopper hook around the appliance's legs to hold it in place. Result: you won't have to resort to a broom handle to root around under your fridge, or pull the whole thing out from the wall, when you lose something to inertia. Just bend over and pick up a single runaway, or sweep larger messes along the bumper into a dust bin.
The Stuff Stopper fits the majority of appliances mentioned above, and is designed to set back a few inches underneath them so it won't be too visible as an attachment.
