The TRK05 is an adapter for TR series posts that prevents the post from rotating during a height adjustment when the post is held in any PH or UPH series post holder. The adapter attaches to the bottom of a TR series post using the included low-profile 1/4"-20 or M6 cap screw. A key on the TRK05 fits precisely into the machined channel in the PH and UPH series post holders. A TR post outfitted with the TRK05 adapter is shown to the right as the post is aligned and inserted in to the post holder. These adapters are particularly useful when swapping post mounted components to decrease the alignment time. Use with an R2 (R2/M) collar and maintain the post height adjustment for even quicker component swapping.
