MAX RB443T TWINTIER Rebar Tying Tool

MAX RB443T TWINTIER Rebar Tying Tool for Mesh & Rebar up to #7 x #7

The MAX RB443T TWINTIER Rebar Tying Tool gives concrete and reinforcing contractors a faster, more consistent way to tie wire mesh and rebar combinations from #3 x #3 up to #7 x #7. With ties completed in less than half a second and up to 5,000 ties per battery charge, the RB443T helps crews spend less time tying and more time moving the job forward.

Key Benefits

• Completes each tie in less than 1/2 second to help increase crew productivity.
• Delivers up to 5,000 ties per battery charge for longer working time between charges.
• Uses a wire pull-back system that helps reduce excess tie wire and lower material costs.
• Handles wire mesh and rebar combinations from #3 x #3 through #7 x #7.
• Produces a shorter tie height, reducing the amount of concrete cover required over the tie.
• Slim tool arm makes it easier to reach ties in tighter reinforcement layouts.
• Enclosed wire magazine helps protect the wire and internal components from jobsite debris.
• Helps reduce the repetitive hand and wrist movements associated with manual rebar tying.

MAX TWINTIER Technology for Faster Rebar Tying

Dual Wire Feeding for Sub-Second Ties

The RB443T uses MAX TWINTIER dual wire feeding technology to feed two wires at the same time. This allows the tool to complete a tie in less than half a second, helping crews work through large mats, slabs, panels, and reinforcement assemblies much faster than traditional hand tying.

Reduced Wire Use with Wire Pull-Back Technology

MAX's Wire Pull Back Mechanism draws excess wire back into the tool before completing the tie. By using only the amount of wire needed for each connection, the RB443T helps reduce wasted tie wire and control consumable costs over high-volume tying applications.

Shorter, Cleaner Tie Profile

The TWINTIER Wire Bending Mechanism creates a shorter finished tie height. A lower-profile tie requires less concrete cover over the wire and helps produce a cleaner reinforcement assembly before the pour.

Quick Wire Loading

The RB443T includes a wire-loading assist mechanism designed to make loading the dual-wire system faster and easier. This helps reduce downtime when replacing coils and gets the tool back into production quickly.

Built for Tight Reinforcement Layouts

A slim arm design helps the RB443T reach into tighter reinforcement configurations where space is limited. A positioning marker also helps the operator see and line up the location of each tie.

Jobsite Durability

The enclosed magazine helps shield the tie wire and internal tying components from dust, dirt, concrete debris, and other jobsite contaminants. This added protection helps support dependable operation in demanding construction environments.
