Double-tension

Double-tension is a method of applying tension to drum heads.

Drum manufacturers use several methods to apply tension to drum heads; the preferred way is to tighten the heads with a hoop that is held tight to the drum shell with a number of individual threaded rods which connect to stanchions mounted with bolts onto the outside of the drum shell.

When there are individual stanchions for both the lower head and the upper "struck" head, or when there is one common center-mounted stanchion that accepts the threaded rods from both the upper and lower drum heads, that is said to be a double-tension drum.
