Abstract: A molding (1) for use together with floor panels (2). The molding (1) is provided with a first and a second distal edge (3I and 3II, respectively), the distal edges (3I and 3II, respectively) being provided with means for locking a first distal edge (3I) of a first molding (1) to the second distal edge (3II) of a second molding (1). A joint (101) constituted for mechanical locking between panels, the joint (101) having a first edge (101I) and a second edge (101II). The panel have an upper side (103) and a lower side (104), the first edge (101I) having a lower cheek (102). The lower cheek (102) has an outermost portion (102I) and an innermost portion (102II). At least one groove (105) is present on the lower side (104) of the panel, the groove (105) being arranged in a position between the innermost portion (102II) and the outermost portion (102I). A base portion (105I) of the groove (105) is located at a predetermined distance (L) from the upper side (103).
