Abstract: A power tool and a replaceable anti-slip pad for use on sloping surfaces roofers is provided wherein the power tool is provided with a sheet or layer of hook fasteners of the hook-and-loop type fastener system disposed on a side surface thereof, and wherein a replaceable anti-slip pad is provided having a sheet or layer of the complementary loop elements provided on a flat surface thereof. The anti-slip pad is constructed of a high density, closed-cell foam that provides greatly improved traction on roofing surfaces, thereby improving the ability to securely place the tool on the sloping surface without substantial slipping of the tool, which improves worker safety and productivity or efficiency, and provides adequate durability to make the replaceable anti-slip pads cost justifiable, when factoring in the improved productivity. The anti-slip pad is installed and removed from the power tool in the conventional manner in which two object are fastened and unfastened by the use of hook-and-loop fasteners.

Abstract: A shoe having a replaceable sole pad for use by roofers is provided wherein the shoe has a thin lower flexible portion with a sheet or layer of hook fasteners of the hook-and-loop type fastener system disposed on a bottom surface thereof, and wherein a replaceable sole pad is provided having a sheet or layer of the corresponding loop elements provided on an upper surface thereof. The sole pad is constructed of a high density, closed-cell foam that provides greatly improved traction on roofing surfaces, thereby improving worker safety and productivity or efficiency, and provides adequate durability to make the shoe with the replaceable soles cost justifiable, when factoring in the improved productivity. The sole pad is installed and removed from the shoe in the conventional manner in which two object are fastened and unfastened by the use of hook-and-loop fasteners.
