The Victorian collection by Nostalgic Warehouse is characterised by a distinctively pointed peak with a floral design, intricately detailed around the edges of the plate. The Victorian design is a reproduction (although slightly widened to accommodate pre-drilled doors) of Yale & Towne's "Largo" hardware from around 1910 and is in the Flemish Renaissance style. The style has been modified slightly to fit on modern pre-drilled doors. This passage set has an active latch with no locking mechanism. This set will work on doors between 1 3/8" to 1 3/4" thick.
