Place the attachment straps over a secure bar, grommets or ceiling hooks. Also, make sure you have a safe place and enough space to hang the gymnastic rings.
Hold the buckle as shown in the picture so that your thumb is at the top. Make sure that the strap is not twisted. Open the buckle with your thumb.
Feed the end of the strap through a ring and then through the open buckle from below. Fasten the strap by loosening the thumb. Make sure that the strap is not twisted. Carefully check that the strap is securely fastened in the buckle before putting your body weight on the rings.
Make sure the buckle hangs freely and is not in contact with the wooden ring or other objects. If necessary, fasten the excess strap with the velcro fastener.
