Panduit is a wide-ranging supplier with a strong selection of wire management products. One product in their wire management catalog is H100X034H1T, which can also be found with a -B suffix. The price difference between these two is significant despite there not seeming to be any parametric difference; what gives?
The price difference comes from order quantity. QTY. 1 is a single roll of labels for each part number, with the base number H100X034H1T being 1000 labels. The -B indicates a larger roll of 5000 labels, instead. The product is the same either way, only label quantity differs.
