Why Ultra Drain Plus
Clip-in alloy topThe alloy top clips into the base. Once the channel is haunched in concrete, the surrounding compression holds it firmly in place.
Wall-locking armUDP 130 has an innovative wall-locking arm so the walls stay 100% rigid on commercial projects.
Tamper-resistantThe alloy top and base can be locked together to stop tampering in public spaces such as hospitals and parks.
UV protectedThe alloy top covers the top edge of the base, eliminating potential UV issues.
In-built 6° fallEvery UDP base has a 6° fall built in to help reduce, if not eliminate, water pooling.
Interlocking joinsThe interlocking system joins seamlessly inside the channel, and gluing the outside gives exceptional joint strength.
Honeycomb optionThe alternative honeycomb top in 6063A aluminium alloy adds strength and makes trapped leaves easier to clear.
