Vehicle cabs would come in 1981 with a pair of elements called the 4x4 hinge roof and hinge roof holder, which were released alongside a pair of interlocking 1x2 hinge plates. Together, these four components initiated a new family known as finger elements, derived from their ability to join via protrusions that interlaced like two hands coming together. These types of hinge would be used extensively throughout not just LEGO Town but the entire LEGO product portfolio, until being replaced by friction hinges in 1999.

Finger Hinges were introduced in 1981.
