ANTIMICROBIAL REPLACEMENT KITS – The materials of the primary grip areas and have been reformulated with an antimicrobial additive. The additive is silver ion based and will not only inhibit the growth of bacteria, fungi and algae on those surfaces, but help maintain a cleaner surface in general. These should be strongly considered by stores looking to re-open their bulk sections serving the general public. It is a less expensive alternative than replacing the entire spout or bins completely. They are currently only available in 2, 5 and 15 Pack quantities. These Kits work with all Best Bins and Pet Silo spout assemblies.No fee handle recycling is included.
