Product details:

Non-slip stair treads are easy to install and provide permanent traction to help prevent slipping hazards. Non-skid tapes, adhesives, and salts can quickly add up in time and money. These safety treads are inexpensive, take just minutes to install, and have a rust-free aluminum construction with a lifetime guarantee. The treads can be installed on nearly any type of surface, such as wood, masonry, concrete, or metal, using just four screws (not included - #8 stainless steel screws recommended for wood; Tapcon anchors recommended for concrete installation). The non-slip strips not only work great for stairs, but can be used on porches, docks, ramps, trailer or tractor steps, curb cuts, or just about anywhere that water, sand, or snow can make walking slippery. Non-slip stair treads can be used for home or commercial applications, both indoors and outdoors.
