The CrownSF-R features the same locking speed feed ring that fits securely in place on the CTRL, Spire IR, IR², Spire III and Spire IV.
The main difference with the CrownSF-R is each finger is co-molded from two materials and functions without springs. The soft elastomer hinge base allows the SF-R to reload with ease, while a more rigid exoskeleton layer locks each finger into place and minimizes paint from spilling back out of the loader.
The five toolless removable fingers allow for easy cleaning and replacement if necessary. A spare finger is included.
