The QR4-EQ Quick Release Plate from 3 Legged Thing is a camera plate with 1 4 -20 stainless camera screw and a rubberized anti-twist surface. It has a standard Arca-type 1.5 base and is also compatible with Peak Design Capture quick releases and devices. Two 2.5mm security screws prevent the plate from accidently slipping off the quick release clamp.
