[Internal Mast Jacks]

The series of internal mast jack cylinders are laid out for permanent installation in the mast step. Fashioned entirely from stainless steel, both the cylinders and fittings meet all the necessary requirements for corrosion resistance. 

The cylinders are screwed into the mast base from above before the base itself is attached to the mast.
