Utilizing over 30 years of engineering experience, Chicago Clamp Company was founded with the mission to create a new, safe, structurally-reliable, and economical standard for framing roof openings and supporting and distributing loads from joists. For decades, contractors have used traditional welding and cut-angle methods. These methods require certified welding which can be expensive, complicated, and hazardous; if done incorrectly it can compromise the integrity of the joist. To eliminate these inherent project risks, Chicago Clamp Company has developed three easy-to-install Clamp Systems. Each of these Chicago Clamp Systems® preserves the integrity of trusses and saves installation time and money.
