{"product_id":"rattleware-round-stainless-steel-knock-box","title":"Rattleware Round Stainless Steel Knock Box","description":"\u003cp class=\"product-lead\"\u003eThe Rattleware Round Knock Box is a stainless steel espresso puck disposal box built for home and professional coffee stations where counter space is limited. Its round profile measures 6.25 inches in diameter, and the rubber-coated knock bar and rim reduce noise when clearing a portafilter between shots.\u003c\/p\u003e\n\n\u003ch2\u003eBuilt to Handle Daily Use\u003c\/h2\u003e\n\u003cp\u003eThe Rattleware Round Knock Box is constructed from high-grade stainless steel, a material that resists staining, holds up to repeated impact, and wipes clean quickly between uses. For anyone pulling multiple shots a day, a knock box that degrades, cracks, or retains odors is a recurring frustration. Stainless steel avoids all three. The smooth interior also makes rinsing straightforward, with no crevices to trap spent grounds.\u003c\/p\u003e\n\n\u003ch2\u003eQuieter Operation at the Bar\u003c\/h2\u003e\n\u003cp\u003eThe knock bar is rubber-coated, and the rim carries rubber dampening as well. Both contact points absorb impact rather than transmitting it, which meaningfully reduces the sharp crack that bare metal knock boxes produce. In a home kitchen or a shared workspace, that difference is noticeable across a full morning of service.\u003c\/p\u003e\n\n\u003ch2\u003eA Compact Footprint That Fits Most Stations\u003c\/h2\u003e\n\u003cp\u003eThe round design keeps the knock box's counter footprint tight at 6.25 inches across, so it fits alongside an espresso machine without crowding a grinder or tamping mat. The cylindrical shape also holds a useful volume of spent pucks before it needs emptying, without requiring the longer rectangular footprint some knock boxes demand.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHigh-grade stainless steel body:\u003c\/strong\u003e durable, stain-resistant, and easy to clean\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRubber-coated knock bar:\u003c\/strong\u003e absorbs impact and reduces noise when knocking out pucks\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRubber-dampened rim:\u003c\/strong\u003e further reduces sound and protects the portafilter\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRound compact profile:\u003c\/strong\u003e 6.25 inches in diameter, suited to tight counter setups\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\u003eSpecification\u003c\/th\u003e\n      \u003cth\u003eDetail\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eMaterial\u003c\/td\u003e\n      \u003ctd\u003eHigh-grade stainless steel with rubber-coated knock bar and rim\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eDiameter\u003c\/td\u003e\n      \u003ctd\u003e6.25 in\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eHeight\u003c\/td\u003e\n      \u003ctd\u003e7.5 in\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003ePackaged Dimensions\u003c\/td\u003e\n      \u003ctd\u003e8 x 8 x 7 in\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShipping Weight\u003c\/td\u003e\n      \u003ctd\u003e45 oz\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 Round Knock Box suits home baristas and small café stations that pull espresso regularly and want a durable, low-noise disposal solution with a compact counter footprint.
