ZN-9DX This round base version of the ZN-9 iambic paddle cover is available in colored plastic for a $ 10.00 additional charge.
We use Optically Clear, molded Acrylic. 1/4" plastic is used for most models. A box-end, "dove tail" joint is used to join the pieces. There is NO glue used as it will foul the contacts and attack the finish on the keys.
Any engraving (ie. callsign) is done on the inside so it will not collect dust.
