RAM® Pin-Lock™ 6 針安全旋鈕 適用於 C 尺寸及擺動臂

Finally got around to swapping out the old plastic knobs on my C-size arms, and the 5/16"-18 female threading made installation a breeze. Much more secure feel when tightening down, no more slipping when I hit a bump.

Finally, a knob that stays put without needing constant tightening. The 6-pin security lock is a nice touch, and it fits perfectly on my 1.5" C size arm mounts.

I was tired of my old knob loosening up, so I swapped it for this one with the 5/16"-18 threads and it locks down perfectly on my 1.5" arm. The included key knob gives me peace of mind that nothing will wander off.
