Product overview
The SCHOEPS ST 20-3/8 is a mounting cylinder of 20 mm diameter that fits the TEF tabletop mounting adapter and offers a 3/8" thread for table stands.
The cylinder is inserted into the TEF elastic suspension. Its 3/8" thread can hold a support rod or a gooseneck, such as the TM RS 420 L38.
There are two notches in the sides of the adapter through which the cable or cables can be passed. Alternatively the cable can be passed through the centre: a hole drilled in the top takes a miniature cable, with the connector removed for this purpose.
The adapter exists in a short version for mounting in a TEF table flange and a long version for use with two AF 1 table flanges.
