Rubber stopper for french hooks. The first time you put these on the wire, screw or twist them on, rather than push them. Subsequent times, they will push on. The ones we have available now are clear.
NOTE: Better Quality vs. Economy
In the Economy line, the wires are a bit stiffer and more brittle; if there is a moving part, such as the hinge on a lever-back,
this is not constructed as well, and will not be as durable. Of course, there are big differences in price.
