BASICS LBWC50 Indicator Thumb Turn and Release for Mortise and Tubular Locks

The BASICS LBWC50 Indicator Thumb Turn & Release from Formani shows red or green in the window — vacant or engaged — so anyone in the hallway can tell whether a bathroom or bedroom is free. It works with European mortise locks and North American tubular bolts alike. The piece belongs to the BASICS collection, a full range of hardware and accessories for doors, windows, furniture and cabinetry.
