E.R. Butler & Co. is pleased to offer the E. &  G.W. Robinson collection of Early American pressed and hand-ground crystal door and cabinet knobs.

For centuries crystal knobs have adorned doors, cabinets and drawers; their clarity and brilliance continue to suggest the “cleanliness, purity, refinement and good taste” for which they were valued in the nineteenth century

E.R. Butler & Co., as the successor to E. & G.W. Robinson, continues to produce crystal knobs of superior design and workmanship. Our crystal knobs attach to their solid brass turned shanks with a technique patented by Enoch Robinson in 1837. With his “Method of Attaching Glass Knobs to Metallic Sockets” a denticulated knob is held in place by a keystoned socket. Our collection includes an historic variety of shapes, colors and sizes. Round, oval, octagonal or faceted knobs may have concave, flat or full surfaces. Crystal knobs may be clear, milk, opalescent, amber, ruby, ox-blood, amethyst, cobalt, emerald or black, as well as silvered or etched.

Knobs range in size from 2 14 and 1 34 inch diameter and projection for doors to 1 14 inch for cabinets and fine furniture. Shank types are available in many decorative finishes; all knobs are fully complemented by architectural trim including hinges, handles, locks, cane bolts, cylinder rings and covers, key escutcheons and covers, thumb turns, doorstops, etc.
