Inspired by decorative Victorian-era design, the Iver Stirling lever brings ornamental detail to interior doors. This Rectangular Backplate Passage Kit includes a pair of levers and a 60 mm split-cam tube latch for doors that do not require locking, such as living rooms, hall doors and laundries. Each backplate is 240 mm high and 38 mm wide; the lever projects 62 mm, with 205 mm centres. Iver notes the kit includes the components required for the door to function.
