The "Versa II" one bay rack is the most versatile single rack that you will find anywhere at any price.
You decide the configuration that suits your studio and your needs. The "Versa II" one bay rack is packaged with everything required to set up the rack straight or at the (very ergonomic) 25° angle. Add a set of optional casters for mobility, then choose the trim and other accessories that will make it the perfect and personalized fit for your studio.
For a basic rolling rack for auxillary gear, this is the best. Build quality and design are superb. Nicely vented to avoid heat buildup, and the optional rear fabric cover means clients don't have to look at cable spaghetti if the back is facing them. Price is a high, but it probably should be.
