We invented this technique. These are perfect.

Dampeners mean you can strike the bump key repeatedly, without having to reset the key each time. They also work to perfectly space your bump key, so you know you have the key in the right place to open the lock. Real bumping, real technique.

• Correct selection of sizes and materials.
• Tough, durable, long lasting
• Perfect spring and tension provided

I was the first person to use this technique and over the last decade have perfected both the technique and the tools to do it. Get the right Dampeners the first time, and save yourself the hassle.

Many people supply dampeners that are all the same size, same material and simply not right for the job, the selection must allow you to create the correct depths you need for successful bumping.

Additionally, without the shoulder removed, the bump key soon starts cutting into the 'incorrect' dampener, which then changes the depth of your key.  Because we invented this technique, we went thought literally hundreds of different products, shapes, sizes and materials, and what you get in this set is all that hard work done for you.
