# Otari NAB Adapters

There are several types of Otari NAB adapters, but this article is about this one:

These adapters have a rubber belt along the side that is often broken after all thee years. I measured the dimensions of the belt and here it is:

<table border="1" id="bkmrk-width%3A-7-mm-thicknes" style="border-collapse: collapse; width: 100%; height: 178.21px;"><colgroup><col style="width: 22.2745%;"></col><col style="width: 77.7146%;"></col></colgroup><tbody><tr style="height: 29.7017px;"><td style="height: 29.7017px;">width:</td><td style="height: 29.7017px;">7 mm</td></tr><tr style="height: 29.7017px;"><td style="height: 29.7017px;">thickness:</td><td style="height: 29.7017px;">1,5 mm</td></tr><tr style="height: 29.7017px;"><td style="height: 29.7017px;">folded in half: </td><td style="height: 29.7017px;">~ 100-105 mm</td></tr><tr style="height: 29.7017px;"><td style="height: 29.7017px;">diameter:</td><td style="height: 29.7017px;">~ 64 mm</td></tr><tr style="height: 29.7017px;"><td style="height: 29.7017px;">circumference:</td><td style="height: 29.7017px;">~ 200 mm</td></tr><tr><td>radius:</td><td>~ 32 mm</td></tr></tbody></table>

Also beware of the 6 (3x2) small pucks that can -and will!- fall out when you remove the rubber belt.
