Mayline ARC Rotary File System employs a unique construction with a turning configuration that results in a double-faced storage unit with an easy access to both sides. This ARC Rotary Adder Unit can be attached to either side of your Starter System allowing to create and alternate your storage space as required. Experience the benefits of a high density storage, enhanced security, easier file retrieval and smart modular design. The Adder Units are available in a great number of configurations to meet all of your individual storage requirements and fit your current Starter ARC Rotary File System.

High Density Storage
This Mayline ARC Rotary File System employs a unique rotating construction that creates a back-to-back storage unit. This particular file storage technology almost doubles your storage capacity while providing instant access to all files from both sides. The shelves fit different file formats and allow 5.25" of letter depth or 6.50" of legal depth clearance from wall for the rotating carriage. The shelves adjust on 1.5" high increments and feature a weight capacity of 120 lbs each. The storage space is intended to easily fit end-tab or top-tab filing, binders, supplies and other materials.

ARC™ Smart Design
The unique design of ARC Rotary File System aims to bring numerous benefits to the end user. The rotating mechanism allows easy pull or push rotation and self-locates every 90 degrees so that the storage module self-positions to provide easy access to the contents from both sides. To ensure easy in-field adjustment options the system features a cantilever designed shelving technology. The storage space is lockable on both sides for extra privacy and security. The lock is positioned on the waist height.
