【Neck Strap with NATO Rails】 This gimbal belt kit is compatible with DJI Ronin RS4 RS4 Pro RS3 Pro RS3 RS2 RSC2 SC handheld stabilizers. Directly attach the two mini quick release NATO rails to the built in NATO ports of RS 3 Pro RS 2 RSC 2, or the "Ronin Series Accessories (RSA) Ports" of Ronin S and Ronin SC before connecting the neck strap. It helps reduce fatigue for long handheld shooting sessions and improves stability for capturing smooth and professional video footage | 【Two 1/4" Screw D Ring Attachment】 Securely connect the gimbal stabilizer shoulder neck strap to the mini NATO rails via the 1/4" screw D rings. You can also attach the D ring screws to our ST49 Sling Handle to transform it into a shoulder strap for one handed stabilization and lower angle shots or combine it with our GA006 Dual Handgrip for added stability and better arm support. Also compatible with SmallRig stabilizer accessories | 【Free Strap Length Adjustment】 The RS2 RSC2 RS3 RS3 Pro RS4 RS4 Pro gimbal neck strap length is adjustable from 41.7" to 57.5" (106 to 146cm), so you can customize the fit according to your body shape and height and get an optimal wearing experience for any creation, such as vlogging, live streaming, filmmaking, and photography | 【Soft Comfortable Shoulder Pad】 The soft and breathable shoulder pad can evenly distribute the weight to reduce muscle stress and avoid shoulder pain. Additionally, it increases stability and prevents the shoulder strap from slipping off when filming on the go | 【Pair with More NEEWER Products】 Attach the neck strap to our A104 universal phone cage video rig, PA023 PA024 phone cage for iPhone 15 Pro/15 Pro Max, PA021 S23 Ultra phone cage, CA003S ZV-E10 cage, CA043 X-S20 cage, and CA041 Z8 cage for enhanced stability when shooting with both phones and cameras. Additionally, individual NATO rails can be used on any camera cage to attach top and side handles, such as our CA008 Top Handle and CA023H CA017H Side Handle
