A most innovative and handy tool particularly for use on plastic pipe or polished surfaces. The standard Boa is more than capable of exerting up to 2 tons of pressure, more than enough for even the most stubborn thread. Because it utilises a rubber strap it will not mark or scratch the surface. The Baby Boa has a 150m(6") handle and is capable of gripping objects up to 100mm(4") diameter whilst the standard Boa is 200mm(8") long and will grip up to 150mm(6") diameter. Of course these tools are just as useful on a huge variety of other jobs, removing oil filters, tap covers, the most stubborn of pickle jar lids, particularly for those of us whose grip is not what it used to be. No home should be without one.
