What type of drawer slides do quality mobile pedestals use?

Commercial-grade mobile pedestals use ball-bearing full-extension drawer slides rated for 50–100 lbs — full extension means the drawer pulls completely out for full access to the back of the drawer. Cheaper units use partial-extension slides that block rear drawer access. File drawers should use full-extension slides rated for at least 50 lbs to handle hanging file loads without drooping. At OfficeFurniture2go.com, all commercial pedestals use full-extension ball-bearing slides — call 1-800-460-0858 to confirm specifications on a specific model.
