Tests performed by Intertek Testing Services NA Ltd. on a standard 5" rain gutter / eavestrough.
Even when most of perforations are blocked, the Clip N GuardMC still efficiently drains without overflowing.
Holes blocked | Water flow |
---|---|
0 % | 29,7" (755 mm) |
50 % | 21,1" (537 mm) |
80 % | 12,6" (321 mm) |
When debris sits on top of the Clip N GuardMC, it can be easily dispersed by a light wind. Wet leaves will dry up quickly and disperse without intervention.
Debris (measured 12" (300 mm)) | Required wind speed |
---|---|
20 dry leaves | Negligible |
200 fir needles | 8 km/h |
20 wet leaves | 10 km/h |
100 pine needles | 10 km/h |
With 312 perforations every 12 in. (305 mm), the Clip N GuardMC can drain 29.7 inches (755 mm) of water per hour per linear foot - 3 times the highest rainfall ever recorded during a storm.
