In a busy coffee shop, a knock box is used repeatedly throughout the day. When its upper section becomes worn or damaged, replacing the entire coffee grounds container may be unnecessary. The RHINOWARES THUMPATOP is a replacement plastic top designed for THUMPA300 and THUMPA860 knock tubes.
It allows you to replace the upper component while retaining the existing container and other serviceable parts. A practical spare part for professional espresso stations and home barista equipment.
1 × THUMPATOP plastic replacement top.
Not included: knock bar, rubber bar sleeve, collection tube or any other components. The existing knock bar may be reused if it is compatible, undamaged and correctly secured.
This product is a replacement component, not a complete knock box or a full replacement kit.
Compatibility should be checked against the existing knock tube model. The nominal tube diameter is not an independently verified measurement of the replacement top itself.
Situation 1 – A cracked or damaged top: If the upper plastic section has cracked, become distorted or no longer fits securely, replacing the top may restore the usability of the existing knock tube, provided the remaining parts are in suitable condition.
Situation 2 – Routine barista station maintenance: If the collection tube and knock bar remain serviceable, replacing only the worn upper component can avoid purchasing a complete new knock box.
Inspect all parts before reuse. A damaged or unstable knock bar should not be transferred to the replacement top.
Remove the knock tube from the working area and empty the coffee grounds. Carefully remove the existing knock bar and worn upper section, following the equipment's applicable assembly instructions.
Position the replacement top on the compatible THUMPA tube, then refit the existing knock bar only if it is in good condition. Check that all components are correctly seated and securely attached before returning the knock box to service.
Do not force the replacement part into position if the dimensions or mounting arrangement do not match.
Clean the plastic component using water, mild detergent and a soft cloth or sponge. Avoid abrasive pads and harsh mechanical cleaning that could scratch the surface.
Hand cleaning is recommended as a precaution. Dishwasher compatibility has not been independently confirmed, so the care icon should not be interpreted as a verified manufacturer prohibition.
Handle the component carefully and inspect it regularly for cracks, deformation or loose fittings, particularly in high-volume commercial environments.
