Lifting straps

A critical component is the lifting strap associated with the end product. Research has shown that a wide variety of straps and belts are available, with the overall safe working load defined by the end fitting used.
We have ralised that the product would increase its versitility if it was offered with a range of straps to suit all situatuions. Therefore the following range of products is being considered:

1. The RLL50E Ratchet Straps is endless and therefore has no end fittings. The RLL50E has a load capacity of 4000Kgf.
