I got the Double 50 Qrt Top mount Waste Container for my shop.  Unfortunately I measured wrong when I ordered them.  But, I didn't want to send them vack, I built a new cabinet that will accommodate the trash bins.  They are very convenient for my application.  I open the door and there are 2 trash cans at my disposal.   No more messy cans in tge open.  You close the door and there is no trash to be seen.
