If your crew still ties rebar by hand, the WL-400B battery rebar tying machine is one of the easiest upgrades you can make to speed up a pour. It's a portable, fully automatic rebar tier that wraps and twists a clean wire tie around each intersection at the pull of a trigger.
What the WL-400B is
The WL-400B is a cordless, battery-powered rebar tier built for portability on the jobsite. Place the head over the point where two bars cross, squeeze the trigger, and it feeds, wraps and twists the wire automatically — no hand pliers, no kneeling and twisting bar by bar.
Why it's worth it
- Faster pours: each tie takes a fraction of a second, so a crew gets through far more intersections per shift.
- Consistent ties: uniform tension every time for a tidier, stronger cage.
- Less fatigue: saves the wrists, hands and back from hours of repetitive twisting.
- Portable: light, cordless and easy to move around the formwork.
Who it's for
Concrete contractors, steel fixers, formwork crews and serious builders working slabs, footings, driveways and walls. If you tie rebar often, it pays for itself in saved labour.
