55mm Thick Steel Cockring — Metal Fat

The largest in the Metal Fat range — 55 mm internal diameter, made for generous sizes or for comfortable long-term wear. At this diameter, the ring compresses without constricting: blood flows, the penis swells, but you retain total freedom of movement.

The large solid steel format

A 55 mm internal diameter corresponds to a circumference of approximately 17.3 cm at the base. This is the ideal size for well-endowed men or those who want to wear a metal cockring without the vice-like sensation of smaller sizes. The thickness of the ring compensates for the larger diameter — compression remains effective, just less aggressive.

Mirror finish and impeccable hygiene

Like all Metal Fat products, the 55 mm is machined from mirror-polished stainless steel, with no seams or rough edges. The metal glides over the skin, doesn't retain any bacteria, and cleans in seconds. You can sterilize it with boiling water, alcohol, or in an autoclave — it won't budge. An investment that lasts for years without special maintenance.

280 g for a noticeable presence

It's the heaviest in the range, and you can feel it. The downward pull is firm, the metal slowly warms up on contact with the body, and every movement reminds you of its presence. For a tryst, the visual effect is unmistakable — the thick, shiny ring at the base draws the eye and highlights the erection. When worn for extended periods under clothing, the weight adds a discreet but constant arousal.
