If you have made the decision to dress up your cabinets with glass cabinet knobs, bravo! Glass cabinet knobs are probably the easiest, yet also most effective way to make a normal cabinet look like an heirloom piece. But now you need to know how to put those knobs on your cabinets.
This process is going to depend on the knob and the cabinet. First look at any instructions or warnings that came with the glass cabinet knobs. You need to remember these knobs are glass, and therefore will have some special guidelines for use, to keep them from breaking.
Next, look at your cabinets. Do you know where you will want the knobs to be on the cabinets? While you can choose to put the knobs in the same place the old knobs were, you may want to reposition the knobs to new places to make them more convenient for your use. One rule of thumb is not to install the glass cabinet knobs closer then one inch to the edge of the cabinet door. Anything closer comes with a threat of splitting the wood and having to get a whole new cabinet door.
If you're not quite sure where to put the knobs, reach up to the cabinet and see what would feel comfortable as a place to pull them open from. Mark that height. Measure the distance from the bottom of the cabinet and then go from door to door, where you will be replacing the glass cabinet knobs and mark the same spot. You want to make sure these are lined up properly so you don't have crooked doorknobs when you think the job is done. Being just a little off will be noticeable.
Generally, installing glass cabinet knobs is easy. You just need one hole and one screw for every knob.
Before pulling out the drill, go back over marks you made for the holes with an awl to make a small indentation. That way, when you put your drill on the dot, it will be easier to hold it in the right place. Also, get a clamp and attach an extra piece of wood behind where the hole is going to be drilled into the cabinet. This will keep the inside wood from splintering as you break through the backside of the door.
Now you can slowly drill the hole into the wood. Once the hole has been made, push the screw through the backside and hold it as you screw the knob in on the front side. Remember, this is glass you are working with, so don’t keep tightening; too much twisting can break the knob.
Some glass cabinet knobs also have extra pieces that need to be put in place when they are being attached. Often there are small rosette shaped metal pieces that will give a buffer between the glass cabinet knobs and your cabinet. Too much rubbing on the cabinet can start to wear down the glass knob and the cabinet wood. The rosette will help it last longer.
