In our office there's a expose iron pipe (water drain), is located between the desk space and the printer, fax (you know the rest) is 5' 10" from the floor. So far my co- workers never had to worry (the tallest was 5'8), went I got the opportunity in this company the warn me about the pipe and my height (I'm 6'2") and I said is ok". I was wrong, one day I was rushing to complete something for a customer and happen... The pipe got me and I was out for couple of minutes.... After that I jump online in search of something and at first nothing but then the name "New Pig", I said let's see and there it was... I saw it and bought it right away... After I did the installation I hit one but was more joyfully than before !! Amazing product for that type of cases !!!
