20140076909 | Painter's Pal - The Painters Pal is a lightweight, portable platform that can be adjusted to a pitched roof, thus allowing it to keep your required painting, but not limited to, equipment level. This allows you to have your hands free for work and safety. The elevation bar and foot, which are detachable, are what allows you to adjust the Painters Pal up and down to achieve the correct pitch; when detached, the Painters Pal can be used on any level surface, creating duality. This tool was designed to assist, but not limited to, a painter. The Painters Pal was designed with three separate compartments so a, but not limited to, one gallon paint can, brush, scraper, rag and even a soft drink can may be transported. With the carrying handle, it can be transported from place to place with no trouble, even up and down a ladder. | 03-20-2014 |
