Ki-RO Core HD

Ki-RO Core HD


The Ki-RO Core Heavy Duty (HD) is stronger and more durable than the Ki-RO Light Duty (LD) and is made with heavyweight polypropylene webbing. It is slightly lighter in weight and material than the Ki-RO HD ProElite.  It is resistant to regular heat, mold, mildew, and is slightly water resistant.  We do not recommend leaving the Ki-RO HD in extreme heat situations for extended periods of time.

We use Dura-grip Brand hook and loop closure for adjustability and metal O rings for connections and resistance. Minimum recommended overlap for adjustment is 4.5" with a maximum recommended load of 75lbs at that overlap.
