Even when most of the holes are blocked, the Golden GuardTM still drains efficiently any rainfall.
When debris sit on top of the Golden GuardTM, they are easily blown away by a gentle breeze. Wet leaves
will dry up quickly and disperse by themselves.
With 312 perforations every 12 in. (305 mm), the Golden GuardTM can drain 29.7 in. (755 mm) of water
per hour per linear foot-that's 3 times the amount of water ever recorded in the heaviest rainfall.
