Rhino Coffee Gear Deluxe Stainless Steel Knock Box

The Rhino Coffee Gear Deluxe Round Knock Box is the premium option in Rhino's knock box range — built from heavy-duty stainless steel for the kind of daily punishment that home and café espresso setups dish out. With a capacity of 30–40 spent pucks and a footprint of 170mm x 170mm x 165mm, it strikes the right balance between generous capacity and practical counter size.

Heavy-Duty Stainless Steel Construction

Where the standard Rhino Knock Box uses plastic, the Deluxe steps up to heavy-duty stainless steel — a material that handles repeated daily impact without cracking, staining, or degrading over time. The smooth stainless steel interior is also straightforward to clean with warm soapy water, and resists absorbing coffee oils and odours.

Quiet Operation, Built to Last

The knock box features both a rubber base and a top rubber gasket, which work together to absorb impact and dampen noise significantly during use — important in a home kitchen, and appreciated on a busy café bar. The rubber-covered knock bar is designed to protect your portafilter basket rim during knocking, and crucially, it is replaceable — meaning the knock box can be maintained over the long term without replacing the whole unit.

30–40 Puck Capacity

At 170mm x 170mm x 165mm, the Deluxe Knock Box holds approximately 30–40 spent espresso pucks. For home baristas this typically means several days between empties; for café use, it handles a solid volume of shots before needing to be cleared. This is a meaningful step up from the standard Rhino Knock Box, which holds around 20 pucks.

Suited to Both Home and Commercial Use

The stainless steel construction and larger capacity make the Deluxe Knock Box well suited to anyone pulling a high volume of shots — whether that's a coffee-serious household, a small office setup, or a café bar. It is built to Rhino Coffee Gear's commercial standard, which means it won't show wear in the way that plastic knock boxes do over time.

Frequently Asked Questions

How does the Deluxe Knock Box differ from the standard Rhino Knock Box?

The main differences are material, size, and capacity. The standard Rhino Knock Box has a plastic body and holds approximately 20 pucks at 150mm x 140mm. The Deluxe is built from heavy-duty stainless steel, measures 170mm x 170mm x 165mm, and holds 30–40 pucks. The Deluxe also features a replaceable knock bar and a rubber top gasket for quieter operation, making it the better choice for higher-volume use or anyone who wants a longer-lasting, more robust option.

Is the knock bar replaceable?

Yes. The rubber-covered knock bar on the Deluxe Knock Box is designed to be replaceable, which means the unit can be maintained over years of daily use without needing to replace the whole knock box. This is one of the key advantages of the Deluxe over entry-level knock boxes.

What are the dimensions and capacity?

The Deluxe Knock Box measures 170mm x 170mm x 165mm (approximately 6.7" x 6.7" x 6.5") and holds approximately 30–40 spent espresso pucks. This makes it suitable for both home setups pulling multiple shots daily and light commercial use.

How do you clean it?

The stainless steel body cleans easily with warm soapy water. The smooth interior resists absorbing coffee oils and odours, so it stays fresh with regular rinsing. The rubber base and knock bar should also be wiped down as part of routine cleaning.

Is it suitable for café use?

Yes. The Deluxe Knock Box is built to commercial standard — the heavy-duty stainless steel construction and replaceable knock bar are specifically designed to withstand the demands of a professional espresso bar. It works equally well in a home setting where durability and capacity are priorities.

Does it make much noise when knocking?

Less than most. The rubber base and rubber top gasket work together to absorb impact and significantly reduce the sound of knocking, which is a deliberate design feature. The rubber-covered knock bar also cushions the contact point between the portafilter and the bar.
