Our custom 3/8"-16 adapter mounts directly onto any of the 1/4"-20 sockets embedded in Anthem One, Anthem Power or Anthem Accessories. Black anodized aircraft grade aluminum with stainless steel inserts.
It's worth noting that we think this accessory is completely unnecessary. Our milled stainless steel 1/4"-20 sockets can withstand more than 1,000 pounds of sheer force. Most industry myths surrounding the failure of 1/4"-20 sockets arose from brass fittings in sheet metal housings. Anthem One and its sockets are industrial-grade engineering designed by engineers who work for Milwaukee Tool and Harley-Davidson.
However, we readily admit there may be an application for a 3/8"-16 adapter and respect your right to buy this stout, robust nugget of metal. Our only concern is to make sure you aren't buying something unnecessarily.
