Sebastian ★★★★★ Oct 23, 2026

Installed this on my forklift mast yesterday and the clamp grabbed the 2-inch square post perfectly without any slipping. The rubber ball holds my tablet mount steady even when I'm driving over uneven warehouse floors.

Stella Y. ★★★★★ Oct 22, 2026

The slotted holes made it easy to position perfectly on my 2-inch square post, and the rubber ball holds my tablet mount securely even over bumpy warehouse floors.

Clamped this onto a square forklift post and the rubber ball didn't budge an inch, even on rough turns. The slotted holes made aligning it with the existing bracket a breeze. Exactly the solid hold I needed.
