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.
