Tying rebar by hand is one of the slowest, most punishing jobs on any concrete site. The RB443T automatic rebar tying machine — often sold as the MAX RB443T — is built to take that pain away, wrapping and twisting a clean tie around each rebar intersection in a fraction of a second, all day long.
What the RB443T does
The RB443T is a battery-powered, fully automatic rebar tier. You position the head over the point where two bars cross, pull the trigger, and the machine feeds the wire, wraps it and twists it tight — no pliers, no hand wire, no kneeling and twisting. It's designed for the kind of repetitive tying that slows crews down on slabs, footings, walls, columns and precast work.
Why crews switch from hand-tying
- Speed: a powered tier completes each tie in well under a second, so a crew can tie thousands of intersections a day instead of hundreds.
- Consistency: every tie comes out with the same tension and wrap, which means a tidier cage and fewer loose intersections.
- Less strain: no more repetitive wrist twisting or bending over for hours — a big reduction in the hand, wrist and back fatigue that comes with manual tying.
- Lower labour cost: faster tying means fewer hours per pour, which adds up quickly across a project.
Key features
- Fully automatic feed, wrap and twist operation
- Cordless, rechargeable battery design for full jobsite mobility
- Built for heavy, repetitive commercial tying
- Lightweight, handheld body for all-day use

Who it's for
The RB443T suits concrete contractors, formwork and steel-fixing crews, precast yards and serious builders who tie rebar often enough that hand-tying is costing real time. If you're running slabs, driveways, footings or structural cages regularly, a powered tier pays for itself fast.
