KNODOS 58mm Walnut Bottomless Portafilter for E61 — Rocket, ECM, Profitec, Lelit, Flair 58

The KNODOS 58mm Walnut Bottomless Portafilter for E61 is a naked portafilter with standard E61 2-ear lugs, a stainless steel body, and a solid walnut handle. It ships with an 18–21g double shot basket and replaces the stock spouted portafilter on any E61 machine — giving you a direct view of extraction from below the basket. Walnut is the most popular handle choice in the KNODOS lineup. Fits Rocket, ECM, Profitec, Lelit, Ascaso, VBM, Bezzera, Quick Mill, and Flair 58.

Works With Every E61 Machine

The 2-ear lug design is the E61 industry standard. One portafilter, one lug pattern, dozens of compatible machines. Quarter turn to lock, flush seat against the gasket, done.

Why Switch to Bottomless

A spouted portafilter hides the extraction. A bottomless one shows everything — channeling, spraying, uneven flow, dead spots. You see it all in real time and can adjust your grind, dose, or distribution to fix it.

18–21g Double Shot Basket

Ships with a stainless steel basket rated for 18–21 grams. Removable for cleaning or replacement with VST, IMS, or other aftermarket precision baskets.

Walnut Handle

Turned from solid walnut — warm mid-tone brown, naturally moisture-resistant, and the most commonly chosen handle across the KNODOS lineup. Heavier than maple, lighter than rosewood.
