Lightweight, Safe and Easy
Prime Design has been the industry’s ergonomic leader since 1992, when we first introduced the concept of an ergonomic ladder rack.
Our design philosophy starts with the worker – how can we make the job safer, easier and more comfortable for the human body? That is because we firmly believe that a product’s design and how it impacts the user is every bit as important as the quality of materials and construction.
The ErgoRack was designed to reduce muscle stress, eliminate risk of injury and speed the job of loading and unloading ladders from a work van.
Easy to use
Deploys with only 2 fingers
Eliminates slip and fall hazards from climbing on bumper or tire

Winner of ergonomic awards in USA, France, Germany, and Australia.

*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.
