Roto introduced the new Roto FS Kempton range. The stainless steel 4-bar hinges are used for top-hung and side-hung applications, are suitable for all frame materials, and can be used up to a 396-pound sash weight. Outward opening windows with integrated friction hinges both limit the possible opening angle of the window and ensure that the sash is held open in any opening angle.
