Vintage-style Hardware Classic & Traditional Timeline Style: Timeless classic style – Early 20th Century up to Modern style interiors Made of genuine glass \”Translucent White – Opal\” color glass 1-1/8\” diameter Silver pan-head screw comes thru glass knob & includes a square nut for fastening May shorten the thru-bolt for accommodation of the material thickness Product Description Specs A classic & original-style round glass cabinet knob in a \”Translucent White – Opal\” color with a silver pan head thru-bolt. This reproduction of the classic round glass knob has been a perennial favorite since the early 20th century on furniture & cabinets of all kinds & is great for use in the kitchen, bathroom, bedroom, & everywhere else in the home. The silver bolt is inserted from the front through the head of the knob & comes with a square nut for the back for tightening. The bolt is smooth-headed & nickel-plated, just as in the old days. Add some character to your home with these very classic & stylish glass knobs. Use only hand tools to install glass knobs on your cabinets. Power tools (or even wrenches) may cause damage to the thread or to the knobs. Insert bolt through head of knob. To tighten, hand turn only the nut on the back of the screw (this is one reason that the heads of the screws are smooth on top and do not have a slot.) Do not turn the knob itself as it may cause breakage. Tighten carefully but do not over-tighten – remember they are made of glass & are by their nature, fragile. We will not replace broken knobs due to over tightening or mishandling.
