SmallRig Shoulder Strap for DJI RS 4 / RS 4 Pro / RS 3 / RS 3 Pro / RS 2 4118 works with a sling handgrip like 3028B, 3028C, DJI sling handgrip or any other one with a 1/4"-20threaded hole on the top to make for more labor-saving shooting. Attach the baseplate to the bottom of a DJI gimbal via the 1/4"-20screw, sling the shoulder strap over your right shoulder, and extend the tripod. When you shoot, just pick up the gimbal; in static shot, it can release almost all stress on your arms. When you don't shoot, just let go of the gimbal and sling it against you front or against your side like a shoulder bag, reducing arm's burden. At both ends of the shoulder strap there are two QD sling swivels that support weight of up to 30kg and provide multiple mounting solutions. Two slide buckles enable easy adjustment of length. Besides, 1/4"-20 and 3/8"-16 threaded holes in the baseplate allow attaching tripods or other devices.
