Drainage Telescopic Riser with Grate MAGNAPLAST Teleskop z kratką B125-12,5T (666410) 12.5T

MAGNAPLAST Teleskop z kratką B125-12,5T is a telescopic drainage riser with an integrated grate crafted for surface and roadway drainage. Designed for installation into existing channel systems, it offers adjustable height to align the grate with surrounding pavement or road level. The B125 load class indicates suitability for vehicle and light traffic areas, while the 12.5T designation relates to the grate and adjustment dimension. The unit directs surface water into subsurface drainage while maintaining a flush, safe finish at the surface.

Advantages

The telescopic design allows precise height adjustment on site, reducing the need for frame modification and enabling quick adaptation to different pavement thicknesses. The integrated grate provides a continuous load-bearing surface that meets B125 class requirements for areas subject to vehicular traffic. Constructed from durable materials, the riser resists corrosion and mechanical wear, ensuring long-term functionality. Installation and alignment are simplified by the adjustable sections, which facilitate retrofitting into existing drainage channels without extensive civil works.

Suitable for

• Roadside and carriageway drainage where B125 load class is required
• Parking areas and light traffic zones
• Retrofit projects for existing drainage channels and slot drains
• Paved surfaces where level adjustment between pavement and grate is needed

Key specifications

• Telescopic adjustable height for alignment with pavement or roadway
• Integrated surface grate designed for vehicular loads consistent with B125 class
• Robust construction for resistance to corrosion and mechanical stress
• Compatible with standard channel profiles for straightforward installation
• Designed to capture and direct surface water into subsurface drainage systems

How to use

Measure the existing channel depth and select the telescopic riser position that matches the surrounding pavement level. Insert the unit into the channel and extend or retract the telescopic sections until the grate aligns flush with the surface. Secure the riser according to the channel manufacturer’s recommendations or local installation practices, ensuring proper bedding and sealing where required. Confirm that the grate is level and that water flows freely into the drainage system before completing the pavement works.

Usage recommendations

Regularly inspect the grate and riser for debris accumulation and remove any blockages to maintain optimal drainage. For installations in areas with frequent heavy loading, verify compatibility with local load requirements and perform periodic checks for wear or damage. Use appropriate fastening and sealing materials suited to the channel type and surrounding pavement to ensure long-term performance.
