Question about stabilizer jacks and landing gear

I use the BAL stabilizers and put two of them on each leg/jack. One goes along the front (or rear) of the rig and the other goes along the long side. that way they are set at about a 90 degree angle to each other. It stops the forward/backward movement, and the left to right movement. If you just use one, it only stops the movement in that direction. Maybe its overkill but it works
