ETA Tool Arms: Torque arms for fastening vertically with electric right angle tools

Torque arms for fastening vertically with electric right angle tools

All arms on this page include RAV-TH (Right Angle Vertical-Tool Holder)  for clamping any tool diameter from 1-1/8″ to 2.0″ (28.6 to 50.8mm). The RAV tool holder allows you to quickly index the handle in one of 12 positions with our precision thumb latch and keep it there indefinitely or change it instantly from fastener to fastener, even on the same assembly.

Most of the time vertical fasteners are driven downward and that is the intended use of the arms on this page. However these arms can also be built to support tools fastening upward from underneath a product as well. Just let us know when ordering that you are driving upward and we can mount the RAV-TH on the top side of the Forearm.

EL-Series arms are meant to be used with electric tools or anything other than air tools. However, all EL-Series arms still require a shop air connection for the float cylinder. Our Air Cylinder gives you the smoothest float of any method and decades of life (more than 50,000,000 rundowns).The volume of air needed is very low, less than 0.03 CFM. A 1/4″ (6mm) ID hose, at 80 psi (5.5 bar) minimum, is more than enough capacity.
