Butted spring steel

The chain braid of the brand ULFBERTH® is characterized by the highest quality and is braided from non-riveted rings 4 in 1. The rings are made of spring steel, which gives the braid a special strength. Individual rings can not easily come loose. We abbreviate this type of braid BTW (Butted Tensile Wire). All chain parts with this abbreviation are made of spring steel rings with an inner diameter of 8mm. All parts are untreated (oiled).
