Library Ladder Bottom Wheel Assembly With Brake

We had a custom bookcase built by a local woodworker. For some reason the wheels he used were industrial strength, ugly affairs. They looked more suited to the wheeled ladders you see at a home improvement store. The spring on one broke (they had been repurposed, were old so the metal springs were brittle). When I found these quiet glide wheels, I was a bit put off by the price, but I needed replacements, so finally purchased a pair. I am absolutely pleased with the quality and they are a much more elegant solution than the original ones. About the only complaint I had was that for the price, the instructions weren't included in the box -- so bookmark this page for easy reference.
