This pre-sloped polymer concrete trench drain kit uses the ULMA U100KX channel with integral stainless steel edging and TDS-exclusive Pedreda pattern decorative grating. The channel has an external width of 130 mm (5.11") and an internal width of 100 mm (3.93"). Channels are 1 meter (approximately 3.3') in length and have a 0.5% slope.
Please note that all raw cast-iron grates begin to naturally rust with exposure to any form of moisture, and will appear bright orange before settling to brown.
