Installation Steps
Standardized procedures for reliable, fast, and secure mechanical splicing on-site.
How To Install Our Couplers
Follow these five critical steps to ensure a compliant, full-tension mechanical splice that meets international structural codes.
✂️ Cut the Rebar
Begin by cutting the ends of the reinforcing bars squarely. A clean, 90-degree cold shear or saw cut is required to ensure the bars butt together perfectly inside the coupler without gaps.
🔨 Cold Forging
The cut end of the rebar is placed into a hydraulic press where it is cold-forged (upset). This process thickens the bar end, increasing its cross-sectional area to compensate for the steel lost during threading.
⚙️ Threading
The enlarged, forged end is then machine-threaded using a specialized threading machine. This creates a standard metric parallel thread that matches the internal thread of the Best Notch coupler.
🔗 Assembly
Thread the coupler onto one bar until it is fully engaged (halfway through the coupler length). Bring the continuing bar to the coupler and rotate it into the open half until both bars meet in the center.
🔍 Step 05: Final Inspection & Tightening
Using a calibrated torque wrench or standard pipe wrench, tighten the assembly to secure the connection. A visual inspection must be conducted to ensure no more than two threads remain exposed outside the coupler on either side. All splices must conform to the project's approved QA/QC protocols.
