By turning the hatch toggles, the coaming presses into the rubber seal of the hatch making the hatch watertight. The degree of water tightness is determined by the number of hatch toggles used, the rubber seal used and the force with which the toggles are tightened. A hatch toggle normally consists of an eye bolt, a mounting bridge and a bow nut or butterfly nut.More information
Eye bolts, bow nuts and butterfly nuts are available in brass and in stainless steel. These materials can be used in various combinations.
Eye bolts are available in various sizes (bolt thicknesses and bolt lengths).
Mounting bridges are available in stainless steel and aluminium.
Hatch toggles are available in two types: with bow nut and with butterfly nut (see images below).
The various types consist of a number of individual components that can be combined in various ways:
Stainless-steel components are always quality stainless steel 316 (stainless-steel plate material and profiles) or A4 (bolts and nuts).
Most components can also be supplied separately.
