Bangers or buckets are the attachment to a rig that acts like the bowl part of a handpipe. A torch is used to heat the bucket to prepare it for the concentrate. After it is heated up, a dab tool is used to drop the concentrate in the bucket and vaporize the product. Some dabbers have a paddle on the opposite side of the point, which is then put over the bucket. The other option at this point is to use a bubble cap. Either way, the bucket acts as the bowl for a rig. These are generally made out of what's called “quartz” glass in order to be able to handle the heat that is needed for these purposes. Make sure to not overheat, and keep your buckets clean or this can affect the flavor of your product and you should replace your bucket.
