U-Rails for underfloor heating – made in Germany & Switzerland
U-Rail for underfloor heating.
The 4018T is the toughest variant of the 40-series for 18 mm pipes – ideal for stiff multilayer composite and PE-RT pipe systems. Its reinforced clamping profile holds heavier-walled pipes reliably in place, even under screed pressure.
