Speedrail Starter (42.4 mm) on 3/8"-16 Thread

The Speedrail Starter turns any 3/8"-16 thread into a 42.4 mm speedrail stud. Screw it onto a 3/8" thread and you can carry on rigging in speedrail with any clamp — a favourite on the GF-Slider. Machined from high-grade aluminium and hard-anodized in Germany by Grip Factory Munich.
