T-TEC LSL Headers and Beams - Tolko Industries

T-TEC LSL Headers

T-TEC LSL Headers are engineered for performance and consistency, resulting in dimensionally stable window and door openings. T-TEC LSL Headers remain straight over time, eliminating problems of cracked drywall and loose nails.


T-TEC LSL Beams are designed to accommodate larger holes and multiple holes without compromising the structural integrity of the product. Produced with a continuous press, these beams accommodate longer spans saving time and money for builders. Trades prefer T-TEC LSL Beams because of the ability to go through the beams rather than around, saving both time and materials.
