The No. 3102 drop ring pull consists of 5 fully CNC machined components that fit together with timepiece precision. Stanchions protruding from the hub are bound by tapered collars which transition into a flaring union with the ring. The ring swells slightly at its midpoint to enable a sure grip. Selective stainless steel wave springs between the ring and decorative hub keep the piece from rattling while under way out to sea. Along with square cups, Lowe Hardware manufactures circular ones with fastenings through their sides.
