Mita RNG20W Heavy Gauge UPVC Round Rigid Conduit 20mm x 3m White

The fixing holes on the Type-RNG should be oversized and screws should not be over-tightened. A gap should be left between adjoining lengths to allow for expansion, 2-3mm will be sufficient for most needs but where extremes of temperature change are possible, a gap of 6mm should be left. Conduit should be able to move freely within saddles or clips and it is recommended that an expansion coupling is installed when a straight run exceeds 6m. All systems are designed to allow installers to comply with current IEE regulations. · · · BS EN 61386-1 and BS EN 61386-21 · · Available in white/black · · High impact · · Durable uPVC · · 3m lengths
