The Rally Repair System is new to the Glass Mechanix injector family. The Rally features a compact stainless steel injector assembly with the most powerful vacuum for its size by using the Glass Mechanix course-thread, ultra-high vacuum design. The Rally is also versatile enough to perform a wide variety of rock chip and crack repairs. Other features include glide-able suction cups, along with center and edge-mount capabilities. The Rally is by far the most effective repair device in its price category.
