Petzl Reinforced Chest Ascender (B16BAA)

This is a small device that helps you climb up a rope by gripping it securely as you slide it up your body. You wear it on your chest and it automatically holds onto the rope so you can move upward safely and efficiently when climbing fixed lines.

• Think of it like a mechanical helper that grabs the rope and holds you as you climb — you push it up, and it locks in place so you don’t slide down.

• It’s lightweight and strong, so it won’t slow you down or take much effort to use.

• The spot where the rope touches is reinforced with steel, making it more durable and resistant to wear.

• You use it together with a hand ascender (like the Petzl BASIC or ASCENSION) — the chest ascender keeps your body centered while the hand device helps you pull yourself up.

. How it works:
You attach it to the rope and your chest harness. As you slide it up, it catches on the rope so you don’t slide back down, making climbing easier and safer.

. Rope size it works with:
For thin to medium ropes (about 8 – 11 mm in diameter).
