Made to evoke European decor, the Matte Black Slip-N-Grip Flat Shoe features a patented design that saves time and money. The Slip-N-Grip Flat Shoe features an internal rubber collar that holds the shoe in place tightly, eliminating the need for set screws, and the tools and frustration it takes to tighten them. These shoes are made of a matte black ABS polymer that will never chip, or have paint flake off. Designed to cover holes drilled into the underside of horizontal handrails, the top of treads and top of balcony floors, the Slip-N-Grip Flat shoes create a consistent look, and add a depth of detail to any stair design. From stair treads, stair railing and a complete selection of Stair Parts, Surewood-LNL has what you need to make your stairs beautiful
