Rain drain

 
new sidewalk concrete with multi-hole drain
Sixty one holes 

 
This multi-hole drain cover features the venerable 1 x 6 x 12 x 18 x 24 hole pattern, resulting in 61 holes to drain rain.  Set in the sidewalk and out of the path of foot traffic, it has acquired a rusty patina.
 
The more unusual 1 x 5 x 12 x 18 x 24 x 30 pattern can be seen here.  
 
Do you have '5' or '6' second ring drain covers?
