Ecoglo® C4171 Black Luminescent Non-Slip Carpet Stair Nosing 2.7 Inch

Model C4171 • C4-E20 Series Ecoglo® C4171 Photoluminescent Carpet Stair Nosing – Black Non-Slip Insert Improve visibility and traction at the leading edge of carpeted stairs with a durable 2.7-inch-wide photoluminescent stair-nosing system. The Ecoglo® C4171 Photoluminescent Carpet Stair Nosing combines a durable clear-anodized aluminum profile, protected photoluminescent step-edge strips and a hard-wearing black silicon-carbide non-slip insert. The specially shaped carpet profile covers and protects the leading edge of the stair while providing reliable traction and visible guidance in normal, reduced-light and power-outage conditions. Designed specifically for carpeted stairways, the C4171 is suitable for commercial buildings, exit stairs, public facilities, hotels, offices, educational institutions and other applications where durable step-edge visibility and slip resistance are required. Product Configuration Model C4171 has a clear-anodized aluminum profile with a black non-slip insert. The adjacent protected strips are the photoluminescent components. The black insert provides traction and visual contrast but does not glow. For the black-anodized profile with a black insert, select model C4271. ✔ Model C4171 ✔ 2.7-Inch-Wide Profile ✔ Black Non-Slip Insert ✔ UL 1994 & ULC 572 Listed Photoluminescent Visibility Protected luminous strips absorb energy from available natural or artificial light and remain visible when normal lighting is reduced or lost. Designed for Carpeted Stairs The specialized aluminum profile is shaped to cover the leading edge of a carpeted stair while creating a durable and clearly defined walking surface. Hard-Wearing Slip Resistance The black silicon-carbide non-slip material is integrally bonded to the aluminum substrate for durable traction in heavily travelled commercial and public stairways. Energy-Free Operation The passive photoluminescent system requires no batteries, electrical wiring or ongoing energy consumption. Ecoglo® C4171 Product Configuration The C4171 combines a clear-anodized carpet stair-nosing profile, protected photoluminescent markings and a black silicon-carbide non-slip insert. Manufacturer Model C4171 Product Series C4-E20 Aluminum Finish Clear Anodized Insert Color Black Recommended Applications Carpeted exit stairways Emergency egress routes Office buildings Hotels and hospitality Schools and universities Healthcare facilities Public buildings Commercial facilities Purpose-Built for Carpeted Stair Edges Unlike a flat stair-nosing profile, the C4-E20 carpet profile includes an extended support section designed to create a secure transition at the leading edge of a carpeted stair. Defined step edge Creates a clearly identifiable leading edge where carpet alone may provide limited visual definition. Protected stair nosing The right-angled aluminum section covers the front edge of the stair and helps protect the carpet transition. Secure installation Designed for installation with polyurethane adhesive and mechanical fasteners.
