Bracket to bolt
 

FRANCE HELICES manufactures all types of brackets.
Because of the large number of angles, FRANCE HELICES has developed a wide range of patterns with an exclusive modification angle system in order to allow any angle of inclination before casting.

The design has been made taking into consideration the following parameters :

 

   - Minimum drag

   - Minimum weight

   - Standard N.A.C.A. profile

   - Air inducting (option)

   - Non cavitation profile.

   - Hub sized according to propeller hubs to avoid hydrodynamic disturbances

Bracket to glass in
 

Collaboration between FRANCE HELICES and boat manufacturer braught FRANCE HELICES to develop a range of brackets to glass-in corresponding to the following criterias :

   - Facilitate the fixing of the laminate,
   - Low sailing drag,
   - Minimum weight,
   - Maximum mecanical resistance.


Contrary to many manufacturers that choose bronze or laiton, FRANCE HELICES choose a coposition of bronzal with 10% to obtain a better mechanical resistance. 60 Kg/mm2 with a lengthening more than 16%. In case of choc, there is a bracket deformation without ruptures of it, the hull is safe.

 

The profile offers a minimum drag, the reduction in weight is then obtained by the increase in mechanical resistance. The well spaced glass-in ribs to allow a good adhesion of the resin :

Production range :

   -20 to 70 mm shaft Ø available.
   -Metric and US sizes.
   - Specials dimensions on request.
