This is a fabulously ornate drop handle. The solid, sand cast, fluted drop is very heavy (particularly the 2.1/2" size) the drop has a built in 'stop' to protect the furniture. It is attached to a brass shank and thread that passes through a thick stamped round backplate and secures inside the drawer front with a steel nut. These drops are expensive but look stunning when mounted.
A note regarding the antique brass finish – These products are created in a traditional foundry using solid forged or cast brass, which is then treated with a solution to naturally oxidize the metal. This dulls the brass finish to give the item an authentic appearance. Note that by nature of the way in which this is achieved, the finish may differ slightly from batch to batch, and may be darker than the image shown. If this is the case, and you would prefer the finish to be a lighter-coloured brass, they can be polished up with a metal cleaner such as ‘Brasso’. This is possible because the finish is left un-lacquered for authenticity
