Chicago Clamp Company’s Chicago Clamp Systems™ provide structurally sound and cost-effective solutions for your roof opening and joist loading projects. These two unique Chicago Clamp Systems™ are engineered and tested with known load capacities and distributions and offer versatile, reliable, and affordable solutions for joist and beam projects.
Utilizing 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 and complicated. To eliminate these inherent project risks, Chicago Clamp Company has developed two easy-to-install Clamp Systems. Each of these Chicago Clamp Systems® preserves the integrity of trusses and saves installation time and money.
