Rhino Coffee Gear Knock Drawer

The Rhino Coffee Gear Knock Drawer is a low-profile, stainless steel espresso knock drawer designed to bring order to a busy coffee workstation. At 348mm wide, 250mm deep, and just 95mm tall, it is designed to sit directly beneath an espresso grinder — using what is typically dead space on the counter to handle grounds disposal, without taking up any additional room. The flat top surface remains usable for tools or accessories when the grinder isn't positioned above it.

A Different Approach to Grounds Disposal

Unlike round knock boxes that sit on the counter and collect grounds in a bin, the knock drawer format pulls out from the front for emptying — keeping the top surface unobstructed and the workspace looking clean and organised at all times. This makes it particularly well suited to compact espresso setups where every centimetre of counter space counts, and to baristas who prefer a tidier aesthetic over the utilitarian look of a standard knock box.

Built-In Venting and Rubber Feet

The sides of the drawer feature strategically placed vents that promote airflow through the grounds — reducing the condensation and odour build-up that can occur in sealed knock boxes over time. Sturdy rubber feet grip the counter firmly, preventing the drawer from shifting during repeated knocking and protecting the work surface underneath.

Stainless Steel Construction

The knock drawer is built from stainless steel throughout, making it durable, easy to wipe down, and resistant to the staining and odour absorption that affects plastic alternatives. The removable knock bar lifts out cleanly for washing or replacement, keeping hygiene straightforward with minimal effort.

Frequently Asked Questions

Can it sit under an espresso grinder?

Yes — this is one of the key design intentions. The 95mm height is specifically suited to sitting beneath most espresso grinders, making use of the space that would otherwise be wasted under the grinder body. This keeps grounds disposal integrated into the footprint of your existing setup rather than requiring additional counter space for a separate knock box.

How does the Rhino Knock Drawer work?

The drawer sits flat on the counter and functions in the same way as a standard knock box — you knock your portafilter against the internal bar to release the spent puck into the drawer below. When it needs emptying, the drawer slides or lifts out from the front, the grounds are disposed of, and it slides back into place. The flat top remains unobstructed throughout, so it can be used as usable counter space.

What are the dimensions?

The Rhino Coffee Gear Knock Drawer measures 348mm wide x 250mm deep x 95mm tall (approximately 13.7" x 9.8" x 3.7"). The low-profile 95mm height keeps it unobtrusive on the counter while still providing sufficient internal capacity for regular espresso use.

What material is it made from?

The knock drawer is constructed from stainless steel, which is durable, hygienic, and straightforward to keep clean. The stainless finish also suits both home and commercial bar aesthetics well.

What are the vents for?

The vents in the sides of the drawer promote airflow through the spent grounds, which reduces moisture build-up inside the drawer. This helps prevent condensation on the internal surfaces and reduces the odour that can accumulate in sealed knock boxes over time — particularly relevant if the drawer isn't emptied after every session.

How does this compare to a standard knock box?

The main differences are format and counter use. A standard round knock box sits on the counter and is emptied by removing a lid or tipping the bin. The knock drawer uses a slide-out or lift-out drawer format that keeps the flat top surface free for use as workspace. It is also lower profile at 95mm, making it less obtrusive on the counter. For high-volume café use, a Deluxe Knock Box or floor-standing Thumpa tube offers greater capacity; the knock drawer is best suited to home setups and lower-volume café bars where aesthetics and workspace organisation are a priority.

Is the knock bar removable for cleaning?

Yes. The knock bar removes easily for cleani
