TRIPOD LEGS There's not much to say about tripod legs other than that they're essential if you're purchasing the 80cm or 100cm Hotdog Slider 3.0. At first I wasn't sure if I needed them. but I'm definitely glad I decided to buy them. When using a gimbal with a slider, these support arms provide additional stability at each end of the slider. end so you can clamp what you need. Each lever is 1/4-20 which makes it very versatile to add to almost any slider. If you plan to create vertical, horizontal or 45 degree slides, this will definitely make your job easier! They are very light and seem well made. With proper care, they last a long time. Again, I would highly recommend them to any slider that needs extra stability and support.
