Halstead and Chidell have introduced 2 'American-style' narrow rims into the range so that the many horn players who prefer this type of rim will be able to use any of the 15 PHC cups.

For Philip Farkas, the ideal rim was one that was 'neither too large nor too small'. An ideal description for these four rims which have long been popular with the many players who find a slightly larger internal diameter rim comfortable.

To meet a demand for an internal diameter that falls between that of the 'AS' and the 'S', these two most popular rims are now available with an internal diameter of 18.00mm.

The advantages of using wider internal diameter rims are immediately apparent. More of the lip is free to vibrate within the mouthpiece, which allows greater mobility over the entire range and gives the potential for developing a greater variety of tone colours.

All 12 rims are available in a choice of 6 finishes and materials- silver plate, gold plate and now surgical grade Stainless Steel and white acetal, black acetal and clear crystalite which are hypoallergenic, has a more constant temperature and a unique 'soft' feel. All of these rims can be used with any of the 15 PHC cups.
