Grey 40mm x 900mm Door Thresholds

Our Grey 40mm x 900mm thresholds are designed to create a clean, durable transition between flooring types while maintaining a modern, neutral finish. Ideal for doorways between rooms, these threshold strips help protect exposed floor edges, reduce trip hazards, and provide a professional, finished look.

Manufactured for strength and everyday use, these 900mm door thresholds are suitable for laminate, vinyl, carpet, and tiled floors. The 40mm width offers subtle coverage without being intrusive, making it a popular choice for residential and light commercial applications. The grey finish complements contemporary interiors and works well with both light and dark flooring tones.
