Building Stronger, Smarter Corners: Wesco Partners with 3WAY® for Modular Excellence

At Wesco, we’re always looking for innovative solutions that improve the speed, durability and quality of modular construction. One of the recurring challenges in our industry is drywall corner cracking — a costly quality-control issue that appears during transport, installation or after occupancy. To solve this, we’ve partnered with 3WAY®, a game-changing product that delivers straight lines, extra strength and long-term crack resistance for inside drywall corner joints.

Why Corners Fail in Modular Construction

Unlike traditional builds, modular units are designed to move. From the factory floor to transportation and installation on site, they undergo stresses that conventional taped and mudded joints simply weren’t designed to withstand. Even the smallest shift can lead to visible cracking in three-way inside corners. This issue not only affects aesthetics but also adds labor, material costs and time-consuming repairs.

For Wesco’s modular and manufacture partners, ensuring a higher standard of durability across all stages of the modular lifecycle is non-negotiable. That’s where 3WAY® comes in.

The 3WAY® Advantage: Strength and Precision Built In

The 3WAY Inside Drywall Corner Joint is not just another tape. It is an engineered solution designed to outperform traditional finishing methods. Here’s why it’s raising the bar for drywall finishing:

• Reinforced Backing – Covers gaps, blown-out board and framing irregularities with confidence

• High Tensile Strength – Cross-fibered paper resists tearing, stretching and distortion, even under stress

• Wafer-Thin Beveled Edges – Make joint treatment easier and help ensure a smooth finish

• Roughened Surface – Enables superior bonding with joint compound

• Accurately Cut Creases – Provides expert folds and straight lines each time

• Greater Durability – Outperforms typical industry paper tape with long-term crack resistance

• 
  

By folding into a precise, adjustable triangle, the 3WAY® adapts to corners seamlessly, eliminating the uneven finishes and future cracks that plague traditional methods.

Easier to Apply, Harder to Beat

Wesco values products that not only deliver strength but also streamline workflow. The 3WAY® was designed with the installer in mind:

• Simple Application – Installs in seconds and requires no specialized skills

• Versatile Use – Can be applied before or after taping, depending on user preference

• Stronger Bond – The reinforced card and roughened surface lock in with drywall mud for long-term stability

• Reduced Rework – Fewer callbacks and less finishing time keep projects on schedule

  
  

The process is straightforward. Apply compound, adjust the flap for fit, press the 3WAY® into place with a drywall knife, and feather out the edges with additional coats. Once dry, it sands smoothly and is ready for finishing.

Built for Modular, Built for Wesco

For modular manufacturers, the difference is clear: 3WAY® drastically reduces the occurrence of corner cracking caused by movement during assembly, transport and installation. By locking adjoining drywall panels together, it creates a reinforced, unified joint that counters the stresses of modular movement, delivering a cleaner, stronger finished product.

This aligns perfectly with Wesco’s commitment to quality, efficiency and long-term performance. Every module we build reflects our reputation, and integrating 3WAY® helps ensure our interiors remain strong and flawless, long after installation.
