NEEWER ST102 2-Pack Aluminum Alloy Camera Slider Support Arm

Key Features
Stable Support- Use these two support arms with your slider on a single tripod to increase stability—no need for a second tripod. Attach to camera sliders with bottom 1/4” threaded hole.
Easy to Carry- Small enough to fit in a tripod bag, the support arm is easy to take on the go.
Extendable Arm- With a maximum load of 7kg/15.5lb, the support arm has an adjustment knob to help you quickly adjust the length and securely lock the arm during shooting. The length can be adjusted from 23.2”/59cm to 37.8”/96cm to meet your needs when using sliders of different lengths. The extendable arm supports your slider in a horizontal position or an inclined position.
