{"product_id":"rattleware-stainless-steel-knock-box","title":"Rattleware Stainless Steel Knock Box","description":"\u003cp class=\"product-lead\"\u003eThe 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.\u003c\/p\u003e\n\n\u003ch2\u003eBuilt for Daily Espresso Workflow\u003c\/h2\u003e\n\u003cp\u003eKnocking 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.\u003c\/p\u003e\n\n\u003ch2\u003eQuieter Knock, Less Counter Vibration\u003c\/h2\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\n\u003ch2\u003eThree Sizes for Different Setups\u003c\/h2\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStainless steel body:\u003c\/strong\u003e resists corrosion and maintains appearance through frequent use\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRubber-coated knock bar:\u003c\/strong\u003e reduces noise and protects portafilter baskets during puck ejection\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThree size options:\u003c\/strong\u003e 6\"x5.5\"x4\", 6\"x5.5\"x6\", and 9.25\"x5.5\"x4\" to suit different counter configurations\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n      \u003cth\u003eSize Option\u003c\/th\u003e\n      \u003cth\u003eDimensions (L x W x H)\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSmall\u003c\/td\u003e\n      \u003ctd\u003e6\" x 5.5\" x 4\"\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eMid-height\u003c\/td\u003e\n      \u003ctd\u003e6\" x 5.5\" x 6\"\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eWide\u003c\/td\u003e\n      \u003ctd\u003e9.25\" x 5.5\" x 4\"\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eMaterial\u003c\/td\u003e\n      \u003ctd\u003eStainless steel body, rubber-coated knock bar\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWho This Is For and Isn't\u003c\/h2\u003e\n\u003cp class=\"product-fit-yes\"\u003eThe Rattleware Knock Box suits home espresso setups and café workstations where a durable, easy-to-clean puck disposal solution is needed.

If you pull multiple shots before emptying, the 6\" x 5.5\" x 6\" version offers additional depth to hold more pucks between empties.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eDoes the rubber knock bar protect the portafilter basket?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eYes. 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.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eWhat is the Knock Box made of?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe Rattleware Knock Box body is constructed from stainless steel.
