The Block-Grip rubber step mats are designed to add safety and security for both indoor and outdoor stairways. Sized at 9.75-inch x 29.75-inch each, these rounded stair mats have a block-like surface texture that is inspired by the type of cobblestone streets you would see in the cities of Europe and Latin America. It is a simple but attractive design that gives these rubber step mats an adaptable visual appeal. They will look great on residential, commercial, and industrial stairways. The primary purpose of the block-patterned surface texture is to improve the grip on your feet while going up and down a set of stairs. It is imperative to have as much traction as possible on stairways because these tend to be the more dangerous and accident-prone areas of a building. Available in packs of 6, these rounded anti-slip stair treads have an extended 1-inch lip that provides for a more firm and stable placement on the steps. Due to the fact that they are made of natural and reclaimed rubbers, these stair treads can be placed in the outdoors exposed to harsh weather conditions for extended periods of time.
