Compatible with 32-gallon receptacles, the Ash Bonnet Flat Top for Trash Receptacles serves two essential purposes. First, the flat top offers an 8-inch opening to encourage people to place their trash inside, rather than throw it on the ground. Adding this piece is in the best interest of the park if you have a large smoking population. Since the Ash Bonnet is on top, it also allows visitors to easily dispose of cigarette buds. Too often, people put their used cigarette butts on the ground, which can make the park look dirty and unkempt. If they do not put cigarettes on the sidewalk, they put it in the trash, which can be a fire hazard. You do not want them to litter, but you do not want the receptacle on fire either, which makes the Ash Bonnet Flat Top for Trash Receptacles a great middle ground. All parts are pre-cut and drilled and holes are slotted for easy assembly to the receptacle. The Ash Bonnet is easy to empty as well.
