Features

  • 0.5-Second Tying Speed
    Tie rebar in just 0.5 seconds per tie, making the MAX RB443T up to 1.8× faster* than previous models. Faster tying helps reduce installation time and improve productivity on construction sites.
  • Up to 1.5× Tighter Ties
    The Wire Pull Back Mechanism delivers up to 1.5× tighter ties*, improving tie strength and helping create more durable rebar assemblies.
  • Compact 12 mm Tie Knots*
    The Wire Pull Back Mechanism reduces the tie knot length from 24 mm to 12 mm*. Shorter knots use less wire while maintaining secure rebar ties.

  • High-Capacity Wire System
    The RB443T produces approximately 265 ties per wire coil for 10 mm × 10 mm rebar combinations and approximately 240 ties per coil for 13 mm × 13 mm combinations. Fewer wire changes help reduce downtime and improve productivity throughout the workday.
  • Lower Operating Costs
    Faster tying, efficient wire usage, and fewer wire replacements help reduce labor time and improve overall jobsite productivity, lowering operating costs.
  • Large Jaw Capacity
    The large jaw design allows the RB443T to tie rebar combinations up to 22 mm × 22 mm, making it suitable for a wider range of reinforcing applications.
  • MADE IN JAPAN
    Manufactured in Japan, the MAX RB443T combines precision engineering with strict quality control to deliver consistent performance, durability, and reliability for professional rebar tying applications.
  • NEW: Wire Load Assist
    The Wire Load Assist system allows operators to replace tie wire without pressing the release button, making wire changes faster while reducing the chance of incorrect loading.
