The JJC QRK-PSK2 includes two sets of quick-release buckle kits, allowing you to upgrade your camera's standard shoulder strap to a quick-detach strap. This quick-release buckle kit is compatible with most cameras' original shoulder straps on the market with a webbing width of less than 11mm. It is suitable for cameras with a strap hole size not smaller than 1 x 2mm. The quick-release buckle's connecting structure is crafted from durable aluminum alloy. At the same time, the main body is made of ABS plastic to prevent any scratches on the camera, ensuring safety and reliability. This quick-release buckle allows you to install or detach the shoulder strap easily. Slide the buckle into the slot to secure it effortlessly, or gently press the square button on the buckle to slide it to the right and release, enabling quick installation and removal for versatile device switching. The woven rope on the quick-release buckle consists of two layers, enhancing weight-bearing capacity for increased safety, stability, and durability.
