Made from recycled and biodegradable materials, these floor-standing bin liners help keep your knock-tube clean and make emptying easy. The liners lift straight out of the tube, allowing for clean, mess-free disposal of spent coffee grounds. There are 100 liners in a roll, each measuring 300 x 1200 mm, and they're designed to fit Rhino's Thumpa 860 or CKTL knock-tube systems.
