If you’re securing loads with 5/16″ or 3/8″ chain, you already know that traditional lever binders are slow, hard on your hands, and rarely get chain as tight as the load actually demands. Speedbinders TD6600BL is the drill-powered answer — a chain binder built for smaller chain sizes that takes the effort out of tensioning and puts it in the drill.
Built for 5/16″ and 3/8″ Chain
The TD6600BL is sized specifically for 5/16″ and 3/8″ chain — the chain range commonly used on lighter equipment trailers, utility trailers, and smaller flatbed loads. Sold as a set of two, it carries a 6,600 lb working load limit, matching the capacity of the chain it’s designed to work with.
This isn’t a scaled-down version of a heavy-duty tool — it’s a binder designed from the start for this chain range, sized correctly so it fits and functions the way a purpose-built tool should.
Drill-Powered Tensioning
Attach a standard cordless drill and the Speedbinder handles the tensioning for you. No bar, no leverage, no fighting the last few inches of travel when the chain is almost tight. The drill pulls the chain to full tension consistently, every time, without the physical effort that wears operators down over the course of a day.
The result is tighter chains than manual binding delivers — not marginally tighter, but measurably so. For loads that need to stay put during transport, that consistent higher tension is the difference between a secured load and one that shifts.
Less Work, More Consistent Results
Every time a tired operator settles for “close enough” on chain tension, there’s a risk. Fatigue-driven shortcuts are one of the most common causes of under-tensioned loads. The TD6600BL removes that variable by making it just as easy to get full tension on the hundredth bind as on the first — the drill doesn’t get tired.
For crews that spend significant time securing and releasing loads throughout the day, the accumulated fatigue savings add up into real hours of more productive, less physically demanding work.
Works With the Drill You Already Have
No proprietary battery system, no special adapters — the Speedbinders TD6600BL works with any standard cordless drill. If you have a drill on the job site (and nearly every contractor does), you have everything you need.
For contractors and haulers working with 5/16″ to 3/8″ chain who want faster, easier, more consistent load securing, Speedbinders TD6600BL is the practical upgrade that makes a daily task significantly less demanding.
