Frameless Glass Entry Systems

In 1942, CASMA began designing and manufacturing hydraulic floor closers in Magenta, Italy. Then in 1953, CASMA extended its product line, becoming the first company worldwide to engineer and manufacture both floor closers and a complete range of fittings for unframed tempered glass doors. CASMA's long experience in this field is expressed in our more than 160 international patents and a vast selection of over 2,500 different fittings for all glass door assemblies.

Today, over 120,000 doors are equipped with CASMA products, each year gracing modern buildings in over 64 countries of Europe, the Middle and Far East, and North and South America. CASMA products offer state of the art technology and sober elegance, and our matchless service is a well known fact in many countries. It is easy to see why you should seriously consider making your doors extremely user friendly while enhancing the appearance of your all glass assemblies with a striking touch of original Italian design, where functions, forms and proportions gracefully blend together.
