I'm looking for pricing on a rabbit manure conveyor belt that measures between 18" and 20" in width, with lengths ranging from 40 to 60 feet. My intention is to assemble two separate conveyor systems, so please provide details on the cost for the required dimensions. Additionally, I'm interested in whether you offer perforated belts. It's important that these belts can effectively retain the manure while allowing urine to drain through. Any information on the options available for this feature would be greatly appreciated. Looking forward to your prompt response!
