Bottle Cap Holder. Keep your bar area tidy and safe with this stainless steel bottle cap catcher! When mounted underneath your wall-mounted bottle opener (sold separately), this device will catch bottle caps as they're popped off bottles. Caps will drop straight down from your cap opener and land directly into this unit's bin. By containing caps in this cap catcher, you're keeping them from collecting on the floor and possibly causing bartenders or other employees to slip on them. This also helps cut down on cleanup time at the end of the day. Create a convenient and functional setup in your back bar area! Made of durable stainless steel, this device has a sleek, professional appearance, is built to last, and easy to clean. A hole located at the top of unit allows for easy mounting.
