Cross-section to scale, from the dimensions IMS publishes for this basket. The border is what seats in the portafilter — not the tamper figure the size is usually quoted by. See why “58mm” isn’t one standard.

That model name is an IMS product code — series, cup count, height and hole pattern are all encoded in it. IMS basket codes, decoded explains how to read one, and lists every code covered here.

This basket is one of a line. See every IMS B64 Competition basket compared — the whole ladder of heights and variants on one page, with the three diameters they share.

Lelit Anna (PL41TEM) (57mm portafilter)

IMS’s B64-series competition basket — the 57mm-tamper series IMS makes specifically for Lelit’s LELIT57 machines (the catalogue names the Anita, Diana and Anna). This is the precision-basket upgrade path for the Lelit Anna; the B70 (58/58.4mm) and B68 (Gaggia-fit) series do not fit these machines. Verified against the official IMS product page and catalogue on 2026-07-06.
