ADH Fine Hardware is pleased to supply the exceptional System M family of concealed pivot hinges. Manufactured by FritsJurgens in The Netherlands, these hinges are concealed within doors when open or closed without typical unsightly side-plates on the bottom of doors.
The newer System M32+ pivot hinge operates on doors up to 770 lbs and has an adjustable speed control for the last 30 degrees of closing, including the last 10 degrees of latching control. This allows for large and heavy doors that are very safe to operate, including being used in regular 105 degree operating doors that would typically function with conspicuous butt or concealed-when-closed hinges.
