Ecoglo® C4261 Yellow Anodized Photoluminescent Non-Slip Carpet Stair Nosing 2.7 Inch
Model C4251 • C4-E20 Series Ecoglo® C4251 Black Anodized Photoluminescent Carpet Stair Nosing – Yellow Non-Slip Insert Improve visibility, traction and emergency egress guidance on carpeted stairs with a durable 2.7-inch-wide photoluminescent stair nosing. The Ecoglo® C4251 Photoluminescent Carpet Stair Nosing combines a durable black-anodized aluminum profile, protected photoluminescent step-edge strips and a hard-wearing yellow silicon-carbide non-slip insert. Its carpet-specific profile covers and protects the leading edge of the stair while providing dependable traction and prominent step-edge contrast. The protected photoluminescent strips absorb energy from available natural or artificial light and remain visible when normal lighting is reduced or lost. The system operates without batteries, wiring or ongoing electrical energy consumption. Product Configuration Model C4251 has a black-anodized aluminum profile with a yellow silicon-carbide non-slip insert. The adjacent protected strips are the photoluminescent components. The yellow insert provides high-visibility color contrast and slip resistance but does not itself glow. ✔ Model C4251 ✔ 2.7-Inch-Wide Profile ✔ Yellow Non-Slip Insert ✔ UL 1994 & ULC 572 Listed Photoluminescent Visibility Protected photoluminescent strips remain visible during reduced-light conditions and power outages after exposure to available light. Designed for Carpeted Stairs The specialized aluminum profile covers the leading edge of a carpeted stair and creates a durable transition between the tread and riser. High-Visibility Yellow Contrast The yellow silicon-carbide insert helps clearly identify the stair edge where it contrasts with the surrounding carpet and stair finish. Energy-Free Operation The passive photoluminescent system requires no batteries, wiring or ongoing electrical energy consumption. Ecoglo® C4251 Product Configuration The C4251 combines a black-anodized carpet stair-nosing profile, protected photoluminescent markings and a yellow silicon-carbide non-slip insert. Manufacturer Model C4251 Product Series C4-E20 Aluminum Finish Black Anodized Insert Color Yellow 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 carpet transition The aluminum profile covers the front stair edge and helps protect the carpet transition from repeated foot traffic. Secure installation Designed for installation with premium polyurethane adhesive and mechanical fasteners.
