MHW-3BOMBER Espresso Knock Box, 1.2L(15 Cups) Coffee Knock Box with Removable Knock Bar and Anti-slip Pads for Espresso Puck, Coffee Ground, Durable Espresso Accessories, Black GB5967B

The MHW-3BOMBER Espresso Knock Box, 1.2L (15 Cups) Coffee Knock Box with Removable Knock Bar and Anti-slip Pads, in Black GB5967B, is built to make your coffee routine a little less messy. It’s a simple tool, but the design is thoughtful.
First, the patent-pending slanted mouth. It is angled so that coffee grounds fall cleanly into the bin instead of bouncing back out at you. No more wiping up stray grinds after every knock. The bottom has a silicone anti-slip pad.
This keeps the box from sliding around your counter when you tap the portafilter against it. It also dampens the noise, so you are not waking up the whole house with a loud clang. Your countertop stays protected too.
The materials are chosen for daily use. The body is made from durable ABS plastic. It won’t crack or warp easily. The knocking bar itself is metal, wrapped in a rubber sleeve.
That rubber sleeve is key—it absorbs the impact and protects your portafilter from getting scratched or dented. It also cuts down on the knocking sound, making the whole action a lot more pleasant.
You don’t need a huge machine for a decent capacity. This knock box holds up to 15 espresso pucks, which is about 1.2 liters of used grounds. The square shape is smart. It fits neatly on a countertop without wasting space, unlike round bins that leave awkward gaps.

Size-wise, this thing is designed to fit most espresso machines. The dump bin has a diameter of 4.5 inches. The height ranges from 3 inches at the shortest to 4.5 inches at the tallest. It fits right onto your drip tray in a space-saving way.

Coffee Knock Box Buying Guide
A coffee knock box simplifies puck disposal. Choose teh best design. After pulling a shot, you need somewhere solid to knock that spent puck out. A flimsy knock box can slide across the counter, make a mess, or even break. The right one keeps your station tidy and your workflow smooth.
Bar Material
The knocking bar is where the action happens. Most are made from metal or plastic. A metal bar—often stainless steel—holds up better over time. Plastic bars can crack or warp under repeated hits. But metal bars can be noisy. If you work in a quiet home kitchen, a rubber-coated bar might be worth considering. It dampens the sound while still providing a firm surface.
Base Stability
Does your knock box slide when you hit it? That’s a common frustration. Look for a base with non-slip feet or a rubber bottom. Some models are weighted to stay put. A heavy base is especially important if you tend to knock hard. A lightweight box might scoot across the counter, which is annoying and can lead to spills. You want your knock box to stay exactly where you put it.
Size and Capacity
Think about how many shots you pull per day. A small knock box might need emptying after just a few pucks. That’s fine for a single espresso drinker. But if you make multiple coffees for your family or host guests oftern, a larger capacity saves you from frequent trips to the trash. Just make sure the size fits your counter space. A huge knock box can feel bulky in a small kitchen.
Ease of Cleaning
Wet coffee grounds get sticky. You don’t want a knock box with hard-to-reach corners. Look for smooth interiors and removable knock bars. Some models are dishwasher safe. Others need hand washing. If you’re lazy about cleaning (like me), a simple design is your best friend. A knock box that’s easy to rinse out will stay cleaner longer.
