Yamaha Tom Holder (Triple Mount Only) YAMAHA Tom Tom Posts & Holders. Y.E.S.S. holders are designed for Yamaha tom clamps which do not drill into the shell. The rod on the ball of the holder is as short as in the main image for Y.E.S.S. holders. 

If you require a tom holder for a drum with a drilled hole for the tom holder, then you do NOT require a Y.E.S.S. holder you should order the standard length ball joint holders and a separate TH904 arm.
