Installing a ladder rack or shelving into your Mercedes Sprinter is essential for transporting equipment, maintaining high productivity, and organization.
But installing an award-winning, ergonomically designed, patented Prime Design solution not only improves carrying capabilities and efficiency; it also lowers injury risks and worker’s compensation claims while eliminating the costs, stress, downtime, and business pressures associated with work-related injuries.
ErgoRack
It’s simple math: Healthy Workers + Thoughtfully Made Equipment = an Efficient Workplace.
ErgoRack eliminates the strain from unloading and stowing heavy ladders onto work vehicles.
This regularly performed operation can get cumbersome, especially when factoring in ladder weights, ladder lengths, operator body types, and vehicle heights. Quite often, a worker takes the unnecessary risk of climbing on a vehicle’s tire or bumper to complete this task.
Prime Design took an ergonomic approach to create a solution that puts work ladders at easily accessible heights, allows for smooth and controlled movements without placing undue stress on the user’s body, and enables deployment or stowage in seconds!

*Three crossbar rack
Crossbar spacing and the vehicle’s wheelbase length will dictate the ladders that can be carried. Crossbars can be spaced at six, seven, or eight feet. A third crossbar can be spaced four, five, six, or seven feet. If carrying a long extension ladder and a short step ladder, a three crossbar rack is suggested. Contact Prime Design customer service for application specific questions. Check the vehicle manufacturer’s recommendation for roof capacity weight limits. A wide range of accessories are available including conduit carriers, lighting mounts, and more.
Van Crossbar Spacing and Ladder Size Guide
| Crossbar Spacing | Step Ladder Size | Extension Ladder Size |
| 4 ft spacing | 6 – 8 ft. | 16 – 20 ft. |
