Concealed hinges

• eliminate gaps
• increase security

These hinges work by rotating about a virtual point, which allows the door to open to 180-degrees with no gap between the door and the frame. The hinges are completely concealed, providing a clean outer panel while eliminating attack points for vandals. Made from stainless steel or zinc-plated steel, the hinges are available in three versions-180-degree free-swinging style, 90-degree free-swinging style and a door-stay style. The 180-degree version is designed for light doors in vertical applications as well as horizontal lids that require 180-degree opening. The 90-degree version is designed for vertical doors or horizontal doors that open from the top, eliminating the need for a door stay. The door-stay style is designed for horizontal lids that open from the bottom and require a stay-open feature. Southco, Concordville, PA. Free info—Circle 610. www.RSLeads.com/110df-610
