AC-TKB
Ultralight AC-TKB with coarse thread bolt. The AC-TKB clamp knob is a new part designed to be used with an AD-1420 and comes as part of the CSK-MBK monitor bracket kit. It is a AC-TK black knob with a 1/4"-20 x 1 1/2" bolt. With the use of the large knob it is much easier to twist and move when needed. Made out of 6061 T6 aircraft-grade aluminum with Type III anodizing . Will work in the harshest of environments, time proven and built to last.
