Sage the Knock Box Dump box

The Sage SEA502BTR the Knock Box 20 is a purpose-built knock box designed to collect spent coffee grounds from portafilters. It offers a compact, durable container intended for manual espresso preparation at home or in small commercial environments. The unit stabilizes the portafilter during knock-out, contains used pucks to simplify disposal, and helps maintain a cleaner workspace next to the espresso machine.

Advantages

The Knock Box 20 features a robust construction that withstands repeated knocks and resists stains and odors from used coffee grounds. Its compact footprint makes it easy to position beside the espresso machine or under a knock rail, while the removable inner bin allows for quick emptying and cleaning. The design minimizes grounds scattering and reduces downtime between shots by providing a dedicated place to discard spent pucks.

Suitable for

• Home espresso setups using a portafilter
• Small cafés or offices preparing manual espressos
• Baristas seeking a tidy workflow during busy periods
• Users who prefer a dedicated bin for spent coffee pucks

Key specifications

• Purpose: collection of used coffee grounds from portafilters
• Capacity: designed for regular disposal of spent pucks in home and small commercial use
• Material characteristics: durable, impact-resistant body with a removable inner container for cleaning
• Size and footprint: compact design suitable for placement beside most espresso machines
• Maintenance: removable components for easy emptying and rinsing

How to use

After extracting espresso, hold the portafilter over the knock box and knock the portafilter against the internal bar to dislodge the spent puck into the bin. If needed, rotate the portafilter to ensure the puck fully detaches. Periodically lift out the removable inner container to empty used grounds into a compost or waste bin and rinse the container with warm water. Allow parts to dry before reassembling.

Usage recommendations

Place the knock box on a stable, level surface close to the espresso machine to minimize movement while knocking. Empty the inner container regularly to avoid buildup and clean by hand with water; avoid abrasive cleaners to preserve the surface finish. For a consistent workflow, use the knock box as part of your standard shot routine immediately after extraction.
