Overhead Concealed Door Closers



BEST remains committed to our practice of rationalizing low-demand products and replacing them with new products with improved design and functionality.

After careful consideration, BEST has decided to discontinue the manufacturing and sales of the CO-50 & CO30 series overhead concealed door closers. The dormakaba RTS88 concealed overhead door closer offers many similar features and benefits and is the recommended alternative.

Please contact your dormakaba representative for additional details on the RTS88 Concealed Overhead Door Closer.
