The EZ adjust perch is machined from aircraft grade billet aluminum for superior strength. Includes a forged lever that has sealed ball bearings for ultra-smooth lever pull. Teflon sleeve allows perch to rotate (or spin on bar) in case of a crash or tip-over. Large round adjuster for on-the-fly adjustments. Rubber dust cover is included. You have seen the cheesy copies or our perch, don?t be fooled. If it doesn?t say ?Works Connection? you are not getting the original or the best. Made in USA.
