Add a vertical ASA to your Sterling with this CNC-machined aluminum extended rail.
Using an Automag vertical ASA, you can now run "VSC" with a bucket changer. Or, if constant air is your thing, add an inline regulator - the easiest way to control velocity on some of the older models.
Select "Arrow" to fit a modern Sterling, or "Classic" if you have a potmetal frame and plastic rail.
Sterling Extended Rail
Each requires a reduced-head M6 flat head screw to attach to the frame. Arrow Sterlings have this screw already; Classic Sterlings relied on the plastic rail stretching. Brass screws with turned-down heads are available for purchase as needed.
Automag ASAs are best mounted with a low-profile 1/4-20 socket head cap screw - which I'll include for upcoming orders.
