The Rattleware Stainless Steel Knock Box is a stainless steel espresso puck disposal box designed for home baristas and café workstations, available in three sizes to fit a range of counter setups. A rubber-coated knock bar absorbs impact and reduces noise during puck ejection. Three size options let you match the box to your workflow and available counter space.
Knocking spent pucks is a repetitive motion, done dozens of times a day in a busy home setup or hundreds of times in a café. The Rattleware Knock Box is constructed from stainless steel, which resists corrosion from wet coffee grounds and wipes clean without absorbing odors the way plastic or coated finishes can. That means the box stays presentable and hygienic through heavy use without needing replacement.
The knock bar is rubber-coated, which does two things: it cushions the portafilter so the bar does not score or scratch the basket flange, and it dampens the sharp crack that a bare metal bar produces. In a shared kitchen or a quiet café counter, that difference is noticeable across a full service shift.
The smallest footprint (6" x 5.5" x 4") fits tight under-group spaces and single-group home machines. The mid-height option (6" x 5.5" x 6") adds depth for larger puck volumes before emptying. The wide option (9.25" x 5.5" x 4") suits dual-group or side-by-side portafilter workflows. All three share the same stainless construction and rubber knock bar.
| Size Option | Dimensions (L x W x H) |
|---|---|
| Small | 6" x 5.5" x 4" |
| Mid-height | 6" x 5.5" x 6" |
| Wide | 9.25" x 5.5" x 4" |
| Material | Stainless steel body, rubber-coated knock bar |
The Rattleware Knock Box suits home espresso setups and café workstations where a durable, easy-to-clean puck disposal solution is needed. The three available sizes accommodate single-group home machines through dual-group or higher-volume workflows.
The Knock Box is designed specifically for espresso portafilter use and is not suited to drip-coffee or pour-over workflows. It does not include a lid or liner.
The 6" x 5.5" x 4" Rattleware Knock Box is the most compact option and is well suited to single-group home espresso machines with limited counter space. If you pull multiple shots before emptying, the 6" x 5.5" x 6" version offers additional depth to hold more pucks between empties.
Yes. The knock bar on the Rattleware Knock Box is rubber-coated, which cushions the impact when the portafilter is struck against it. This helps prevent scoring or scratching of the basket flange compared to a bare metal bar.
The Rattleware Knock Box body is constructed from stainless steel. Stainless steel resists corrosion from wet coffee grounds and does not absorb odors, making it straightforward to wipe clean between uses.
The 9.25" x 5.5" x 4" Rattleware Knock Box is the widest available size and is a practical fit for dual-group or side-by-side portafilter workflows where a larger opening or wider stance on the counter is useful.
