Hello, I am trying to source a company that can sell me Just the hardware to build a library ladder, Most want to sell the ladder as well and I can build , thus save on the cost of shipping as well as the cost of the ladder if I build it to suit my project. What i need is a source for the locking wheels and the track the rest I can figure out for less than than $1,000.00 US I think I’d like to keep some of the dollars in house.If by chance there is a Canadian distributor that would be great(cheaper) but not necessary. Thanks to all. Larry Sivell..really freezing in northern B.C.
