The Odor Hound Gel Wall Mount allows you to place Odor Hound Gel 8 fl. oz. canisters in locations that are most convenient for you. Use the double-sides tape included with each Gel Wall Mount or use wall screws to attach the mount to your walls in areas that require continuous odor elimination. The opening in the bottom of the Gel Wall Mount makes it easy to see if you need to replace your Odor Hound Gel.
