L-L3 Brass Door Knob Spacer
Such a simple item, yet so useful! The doorknob receivers on our backplates are 11/16" diameter. Many old doorknobs, especially glass ones, used tiny stems for the backplates that they made. If you want to use old doorknobs on our plates, this little guy becomes very handy. It simply slips over the old stem, then into our receiver so the knob won't rattle around.
Inner dimension slightly larger than 5/8" to fit receivers up to 3/4".
