Silksong: How I Opened That Ornate Clamp (And Why
Silksong’s ornate clamp in Deep Docks unlocks only with the Diving Bell Key from Act 3, serving as a transit stop, not a puzzle.
Hello, fellow bug with a needle and a questionable sense of direction. I am here to tell you about the time I found an old diving bell in Deep Docks, read the words ‘Its door is shut tight by an ornate clamp,’ and proceeded to lose my mind for a solid hour. If you are searching for how to open the ornate clamp in Silksong, congratulations: you are not alone, and the answer is way less dramatic than the creepy bell suggests. In 2026, with the game fully out and Act 3 no longer a rumor whispered in taverns, I can confirm the truth. The ornate clamp does not open because you hit it harder, shoot it, or stare at it with Hornet’s intimidating mask. It opens only when you have the Diving Bell Key, and that key is tied to the secret Act 3. So if you are still poking around Deep Docks in the early acts, put the clamp on your ‘later’ list and go explore something else. The bell is not a boss room. It is a transit stop.
Wait, What Is This Weird Clamp? 
You find the old diving bell in the deeper part of the Deep Docks. When Hornet inspects it, the game tells you: ‘An old diving bell. Its door is shut tight by an ornate clamp.’ That is it. No prompt, no lever, no nearby switch, no cryptic mural. Just a sealed bell and a clamp that looks important enough to make you think you missed a whole dungeon.
I know the feeling. I circled the room. I checked the ceiling. I hit the clamp with my needle like it owed me geo. Nothing. The reason is simple: the ornate clamp in Silksong is not a local puzzle. It is a progression lock. The only thing that opens it is the Diving Bell Key, and the only place to get that key is the secret Act 3. If you are not in Act 3 yet, the bell is a fancy metal door with trust issues.
The Diving Bell Key Is an Act 3 Thing 
Here is the short version: the Diving Bell Key is obtainable only in the secret Act 3. Opening the bell is part of the natural progression of that secret chapter, so you will eventually reach this moment if you choose to experience Act 3. You do not need to solve a riddle. You do not need to find a hidden wall in Deep Docks. You do not need to sacrifice a Grub to a lamp. You just need to get to the right chapter.
And what is inside? Brace yourself. It is a bench and a speaker. That is it. No boss. No item. No secret boss holding a secret item. The old diving bell is used as a method to travel to the Act 3 area. It is basically public transportation with extra steps and a creepy door. So if you are in Act 1 or Act 2 and the clamp is mocking you, you can safely ignore it. Hornet will not miss out on much, and you will go there anyway if you obtain the quest to do so.
Ballow: The Deep Docks Employee of the Year 
So how do you actually get the key? The Diving Bell Key is given by Ballow, the non-hostile Deep Docks worker who is working right next to the Forge Daughter. The Forge Daughter is a vendor in Deep Docks, and she is the one who points you toward him. After you speak to the Forge Daughter about how to descend below the Deep Docks, she will inform Hornet that she is not the one to ask. Instead, you should be asking Ballow. Go right to the worker and speak to him. He will say that he will wait for Hornet by the bell.
I love Ballow. He has the energy of a guy who has been on break for three years but still clocks in. He does not fight you. He does not judge your build. He just waits by an ancient diving bell and presumably drinks terrible coffee. Once you have done your part, venture to the old diving bell. If you have been there before, you can use the shortcut. If you have never been there, prepare for a long detour. Then climb up the small room on the right to find Ballow. He will operate the descent of the old diving bell. Once ready, Hornet can open the ornate clamp to enter the bell. Inside, sit on the bench, and speak to Ballow to begin the dive.
