Cubicle parts can be extremely difficult to find, unfortunately. There are hundreds of parts and pieces for each cubicle and each cubicle brand manufacturers their own parts, universal parts are few and far between. The best way to find parts for your cubicles is to figure out the make and model (which can usually be found under a file, top cap or work surface) and contact the manufacturer directly or find an office furniture dealer who sells your particular brand. Caution: most dealers aren’t keen on selling a few parts because the profit margin is extremely low. You will have to be persistent.
