We've long offered our 90 Degree Angle Adapter (male) for many years which allows you to attach things such as our Machine Guard at a right angle to a flexible gooseneck or rigid arm: This male version adapter features 3/8"-24 threads on one side and a 3/8" hole on the other. It also includes some hardware: However we recently had an application whereby we needed to connect one of our mounting plates at a right angle to a gooseneck arm. Since almost all of our attachments already have 3/8"-24 male threads we needed a 90 degree angle adapter with female threads. So we made one: This new 90 Degree Angle Adapter - Female also includes some hardware: Now with this new adapter you can connect your attachments at a right angle to your flexible gooseneck or rigid arm. Here we connect our popular VESA mount at a 90 degree angle to a flexible gooseneck arm using the new female adapter: If you have any questions or have a need for a custom solution contact us here.
