Key Specifications

A Knock Box That Hides Under the Grinder

A knock box drawer is the coffee-bar version of a cutlery drawer: a slim steel housing that sits under your grinder, with a drawer that slides out when you need to knock a puck. Normcore says this one fits neatly under an espresso grinder, so it adds a knock station without taking any new counter space. It is the style you see in coffee shops, scaled for a home bench.

304 Stainless Steel Throughout

The body is 304 food-grade stainless steel, and the knock bar is rubber-coated, removable and replaceable. At 5.68 lb it is by far the heaviest pick, which helps it carry the weight of a grinder on top. Cleaning is simple: slide the drawer out and rinse it.

Limitations and Compromises

This is the most expensive knock box in our comparison and has the lowest owner rating, 4.2 stars. Normcore does not publish a puck capacity, and Amazon lists the product dimensions as 6.7 x 6.7 x 1.1 in, which does not describe the drawer clearly. Check the size chart on the listing and measure your grinder footprint before you order.

Setup and Care

Slide the drawer out, tip the grounds into the bin, rinse the drawer and lift the bar out now and then to clean around it.

Who Should Buy It?

• You have a grinder with a flat base and no spare counter
• You want an all-steel, coffee-shop style setup
• You are happy to pay more for a tidy bench

Skip it if you are on a budget or your grinder sits on an uneven base; a countertop box is cheaper and simpler. See every option side by side in our espresso knock box roundup.

SoftPickr Verdict

The Normcore Knocker Drawer scores 8.0/10 and is our best espresso knock box drawer. Price at the time of writing: $89.99. Prices on Amazon move; the live listing is the only accurate source.
