FRAME DETAIL
1.THE INLET REQUIRES THE PRECAST CATCH BASIN TO BE ROTATED 90 DEGREES SO THAT THE
NARROW SIDE IS PARALLEL TO THE CURB. WHEN CALCULATING OFFSETS FROM THE CURB TO
CENTERLINE OF THE PRECAST CATCH BASIN, PLEASE NOTE THAT THE CENTERLINE OF THE
GRATE IS NOT THE CENTERLINE OF THE PRECAST CATCH BASIN.
2.THE DIMENSIONS OF THE FRAME AND HOOD MAY VARY SLIGHTLY AMONG DIFFERENT
MANUFACTURERS. HOOD UNITS SHALL MOUNT OUTSIDE OF THE FRAME. THE HOOD MAY
INCLUDE CASTING LUGS. THE TOP OF THE HOOD MAY BE CAST WITH A PATTERN. SAFETY BARS
ARE NOT ALLOWED ON THE HOOD.
3.ATTACH THE HOOD TO THE FRAME WITH TWO 3/4" × 2" HEX HEAD BOLTS, NUTS, AND OVERSIZE
WASHERS. THE WASHERS SHALL HAVE DIAMETERS ADEQUATE TO ASSURE FULL BEARING
ACROSS THE SLOTS.
4.FOR BOLT-DOWN GRATES, PROVIDE TWO HOLES IN THE FRAME THAT ARE VERTICALLY
ALIGNED WITH THE GRATE SLOTS. TAP EACH HOLE TO ACCEPT A 5/8" × - 11 NC × 2" ALLEN HEAD
CAP SCREW. LOCATION OF BOLT-DOWN HOLES VARIES AMONG DIFFERENT MANUFACTURERS.
SEE BOLT- DOWN DETAIL.
5.ONLY DUCTILE IRON VANED GRATES SHALL BE USED. SEE STANDARD PLANS 204.20 AND 204.30.
