Spline 4.0mm x 870m Bulk

TradeBase 4.0mm Black Foamed Flyscreen Spline – 870 Metre Bulk Roll

TradeBase Foamed Polyethylene Spline is designed to make securing flyscreens easier, faster, and more efficient. Developed specifically for professional installers, the softer, flexible foam construction allows for quicker fitting compared to traditional hard plastic spline. Its design lets you work smoothly around corners, tight spaces, and different frame shapes without the need for adhesives, specialist tools, or excessive force.

The slimmer 4.0mm profile is perfect for caravans, RVs, and motorhomes, where narrower spline channels are the standard. It’s also ideally suited to security doors, older window frames, and any application requiring a finer spline groove. Once installed, the foam naturally expands to hold the mesh firmly in standard 4.0mm spline channels.

Manufactured using 100% virgin materials, it provides consistent size, flexibility, and reliable performance even under varying weather conditions. UV resistance and water impermeability ensure long-lasting durability, whether used indoors or outdoors.

With a sleek black finish, TradeBase Spline delivers a clean, professional look that blends easily into window and door frames. Suitable for both DIY repairs and large-scale professional projects, it’s a trusted solution for securing flyscreen mesh in caravans, windows, doors, partitions, and enclosures.
