Notes: Mukatsuku high quality professional stainless steel cut away dome shape 45 adapter with easy lift off design. 117 grams. Height 27.5mm. Please be aware these adapters are designed that you place the adapter on the spindle and then put the record on the player over the top of the adapter.They are not designed for scratch / hip hop djs who often prefer a very tight fit (like a SL1200 aluminium 45 adapter for example where a dj would have to place the record first and then the adapter on top instead) As all dinked 45 records do not have identical sized dinked holes then you may find a miniscule difference in the space between the adapter and the record. Despite this , there should not be any noticeable dfference in sound quality on playback. For scratch dj's we suggest instead the Mukatsuku Twister mat.
