Recessed U-shaped brushing shoe Grundline PS100 (101×120×4 mm) is a U-profile insert designed to fit into door or frame gaps. Made from galvanized S235 steel with a thickness of 4 mm, the product facilitates fixing wooden elements into concrete while ensuring appropriate separation between the timber and the base. Compatible fasteners: wood screws ø 10 mm or bolts M10. Overall size: 325 × 101 × 120 × 4 mm.

Advantages

The Grundline recessed U-shaped brushing shoe provides a compact, durable insert that supports neat sealing in thresholds or panel joints. Galvanized S235 steel construction offers corrosion resistance and mechanical strength, while the 4 mm thickness ensures rigidity for secure anchoring of wooden members into concrete. The design allows straightforward use with standard wood screws or M10 bolts.

Suitable for

• Sealing door bottom gaps and frame joints
• Anchoring timber elements into concrete foundations
• Applications requiring a recessed U-profile insert for neat finishes
• Thresholds and panel connections where draft, dust or noise reduction is needed

How to use

Measure and cut the recess in the door threshold or frame to match the insert dimensions. Place the U-shaped brushing shoe into the prepared slot so the profile sits flush with the surface. Fasten through the profile using appropriate wood screws (ø 10 mm) or M10 bolts into the substrate to secure the timber element and maintain the required separation between wood and concrete. Ensure the insert is aligned and tightened evenly to avoid deformation.

Usage recommendations

For best results, verify substrate quality and use corrosion-resistant fasteners suitable for the installation environment. When fitting into exterior thresholds, consider additional sealing measures to enhance weather resistance.
