the parted wavy pallet refers to the community's geographical location of the river kahl, which runs through the community. since municipal reform in 1970 the community has been made up of five constituent communities, kleinkahl and kleinlaudenbach on the kahl's left bank, and großkahl and großlaudenbach on the kahl's right bank. edelbach lies somewhat farther away. the river, which rises some two or three kilometres upstream, was in the middle ages a political boundary. the glass on the dexter (armsbearer's right, viewer's left) side is a so-called "spechter" and refers to the local glass production since the middle ages. the tinctures argent and gules (silver and red) are those of electoral mainz, to which the area belonged until 1803. the sinister (armsbearer's left, viewer's right) side shows the arms borne by the family ulner of dieburg, an aristocratic family known to have been in the municipal area from the 15th to the 17th century. the ulner coat of arms was incorporated into the community's arms not only for this family's history here, but rather also to recall the counts of rieneck and schönberg.
