Both the cowls and the rings are made of cast stainless steel. These cowls are revolving and removable. The clamping ring can be fastened by hand, or with a special tool, which is supplied as standard. If the tool is used for fastening, the risk of theft is almost eliminated. A Monel mosquito screen and a stainless steel cover plate to close off the cowl ventilator, can be supplied as an option. Comes complete with threaded ring nut and male deck rinq.
