Powered High-Density Mobile Shelving allows you to customize certain safety features to improve the overall safety of your system and also of what is being stored. All high-density shelving comes standard with safety features that prevent the solution from closing when anyone or anything is in the aisle. You can design your system to have more than just the standard safety features, and we recommend that you do this for systems that are accessed by multiple people at the same time, or any system that is being used by the public. You can also add features that improve the safety of what is being stored. Audit control, password and other locking features, and more can be added to the whole system, or individually by carriage or even drawers and cabinets within the carriages.
