Trim Joist

TrimJoist® is the marriage of an open-web floor truss and a trimmable, wooden I-joist, bringing the best features of each to the relationship. As the name TrimJoist® indicates, this product can be trimmed on the construction site for a custom fit.

Open Web Design
Unlike other solid I-type joists, the TrimJoist® features strut webbing. This eliminates the subcontractor’s need to cut holes. Thus, the valuable floor cavity space is available for plumbing, electrical, and duct work, making them great for use in basements. Say goodbye to drop-down ceilings!

The system's open web design allows subcontractors to easily, practically and quickly run electrical work, duct work and plumbing throughout the flooring system of any building.
