Puck disposal shouldn't slow down your workflow.

A quality knock box handles spent pucks cleanly, withstands thousands of knocks, and keeps the bar station organized — the small tool that makes a real difference in busy service.

The Details

Durable Bar Mounting

Rubber feet or clamp mounting keeps the knock box stable under hard use. Stays in place through thousands of knocks without sliding or tipping.

Stainless Steel Construction

Commercial-grade stainless or impact-resistant materials. Built to absorb the force of commercial tamping without denting, cracking, or wearing out.

Easy Emptying

Wide opening and removable knock bar allow quick emptying between services. Empty in seconds — no workflow disruption during peak hours.

Barista-Friendly Size

Sized for the service station — large enough to handle full puck volumes through a rush without constant emptying.

Ruby K. ★★★★★

The open bottom design makes cleaning out old grounds effortless, and the knock bar is positioned perfectly so you never miss. I was surprised how stable it stays even after a dozen pucks in a row.

Stella ★★★★★

The rubber padding inside is thick enough that I don't wince every time I slam a portafilter down. It holds about a dozen pucks before I need to empty it, which keeps my station tidy during a busy morning rush.

Elizabeth D. ★★★★★

The open bottom is a game-changer for messy pucks — no more scraping or banging to get them out. It’s sturdy enough to handle a full espresso bar’s worth of knocks without budging. Cleanup takes seconds, which saves me time during busy mornings.
