Quad Lock 20mm Ball Top Cap Adaptor

The Quad Lock 20mm Ball Top Cap Adaptor is the premier choice for drivers and overlanders who utilize high-performance 20mm ball-and-socket mounting systems. Designed specifically to integrate with 20mm socket arms—such as those from Tackform, 67 Designs, or Offroam—this adaptor replaces standard phone cradles with the secure, low-profile Quad Lock interface. Featuring a precision-engineered 20mm aluminum ball and a high-strength glass-filled nylon top cap, it provides a vibration-resistant, mechanical connection that keeps your smartphone steady in the most demanding off-road environments. Whether you are navigating technical trails or everyday commutes, the patented dual-stage lock allows for instant one-handed attachment in both portrait and landscape orientations, maintaining a clean and minimalistic dashboard aesthetic.
