Garbage bag holder for a 64 gallon bag?
Im a professional cleaning and I do commercial cleaning and Empty Trash. It hurts my back bending on all the time to hold open the bag to empty barrels. I saw something on QVC about a special rake and it came with a support garbage bag that held the bag open while you dump your leaves in there. Is there something like that u can use to retrieve the waste? It must be for a large garbage bag height (64 gallons)
I do commercial cleaning as well and several of my sites I keep 45 gallon garbage cans on wheels. Place a bag inside and go around dumping the garbage in. I used larger, but then the bags of garbage to go to heavy and a better chance of breaking when you pull to the dump. Also to prevent aspiration of making it impossible to get the trash bag outside, I through some small holes drilled on the sides of the box that allows air to remove the bag easily. Over there are bigger hopper angle you can use your supply store concierge or the door Lowes
