Hi, Try filing cabinet and office drawer runners, I found and liberated some discarded metal drawer trays and runners at work for my heavy stuff.

Seconded for runners from filing cabinets. Office drawer runners are more usually the type you find in kitchen drawers now






. Replacing them with Poltore 725 deep draws, will recover as much as you can expect. Giving me another 0.9sqmish of storage
