This recycling cart is our narrow model with 4 wheels. The bins are loaded from front to back, handles first. Bins are meant to hang over the edge as shown in the photo. Because the narrow recycling cart is only around 26" wide, from wheel to wheel, it is a good choice for those who wish to wheel their cart between 2 cars. We have been in business for over 15 years, providing high quality recycling carts to residential and commercial customers.
