The friction head gives smooth, precise radius setting by simply opening the legs. Both the lead leg and the needle shoe are hinged, so the points can be set parallel and upright when drawing particularly large radii, and ergonomic grip zones help steady the compass.\u003c\/p\u003e\u003cp\u003eStaedtler and their 2024 catalogue agree on a maximum circle of about 360mm without the extension and a length of 146mm. The case holds the compass, a universal adapter and a spares box. The universal adapter clamps common writing and drafting instruments, such as a fineliner, into the compass for inked circles. The lead part and needle are both interchangeable, and the lead part uses a 4mm shank.\u003c\/p\u003e\u003cp\u003eStaedtler's catalogue also lists the 554 as nickel-free.\u003c\/p\u003e\u003cp\u003eCompare more \u003ca href=\"\/collections\/geometry-compasses\"\u003ecompasses\u003c\/a\u003e, the \u003ca href=\"\/collections\/staedtler-geometry-tools\"\u003eStaedtler geometry tools\u003c\/a\u003e and \u003ca href=\"\/collections\/geometry-kits\"\u003etechnical drawing\u003c\/a\u003e range.\u003c\/p\u003e","brand":"Staedtler","offers":[{"title":"Default Title","offer_id":50552425873664,"sku":"SR554 T01","price":30.85,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0863\/5419\/8784\/files\/Staedtler_Mars_Basic_554_Compass_Telescopic_554-T01_1_Mega_Office_Supplies.jpg?v=1791399630","url":"https:\/\/megaschoolsupplies.com.au\/products\/staedtler-554-t01-mars-basic-compass-with-telescopic-extension-bar","provider":"Mega School Supplies","version":"1.0","type":"link"}
