Practical addition for the keyboard table Omega 18810 and the folding tables 18950 and 18953. With the appropriate adapters, the universal holder can be easily attached to the keyboard tables: 18814 for the Omega and 18954 for the folding tables (this is only necessary if the existing support tubes are occupied by other accessories, such as an attachment). The height of the vertical tube can be individually adjusted in 8 levels. The 3/8" or 5/8" threaded connection allows for the attachment of various accessories such as a swivel arm, gooseneck, iPad holder, tablet PC holder, etc.
