Bar Capping provides a stronger hold for the glazing and adds a decorative finish to any greenhouse. The rubber fin also adds a better water seal between the frame and glass. Capping is used in addition to wire clips so in effect will add double protection which is ideal in more exposed areas.
The capping is simply screwed into position using colour coded screws which do not leave any unsightly silver screw heads on show.
Not recommended with overlapping glass.
