This rugged mobile floor stand lets you create a full rolling standing desk workstation with the Rocelco DADR-40 and DADR-46 (Both sold separately). It converts your DADR-40 or DADR-46 desk riser into a fully moveable Sit-to-Stand desk that raises from 34" to 49" above floor level. This can help free the space on your current desk and even allow you to create your own L-desk configuration. Mounting hardware, commercial grade locking casters, and leveling feet included for easy 5-minute assembly and adjustment. Now you can get all the health and productivity benefits of a complete height adjustable standing desk, for a very cost-effective price.
