1. The asymmetry of the Combination Inlet shall be considered when
calculating the offset distance for the catch basin. See SECTION A.
2. The dimensions of the Frame and Hood may vary slightly among dif-
ferent manufacturers. The Frame may have cast features intended
to support a grate guard. Hood units shall mount outside of the
Frame. The methods for fastening the Safety Bar / Debris Guard Rod
to the Hood may vary. The Hood may include casting lugs. The top
of the Hood may be cast with a pattern.
3. Attach the Hood to the frame with two 3/4" x 2" hex head bolts, nuts,
and oversize washers. The washers shall have diameters adequate
to assure full bearing across the slots.
4. When bolt -down grates are specified in the contract, provide two
holes in the frame that are vertically aligned with the grate slots.
Tap each hole to accept a 5/8" x - 11 NC x 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.
6. This plan is intended to show the installation details of a manufac-
tured product. It is not the intent of this plan to show the specific
details necessary to fabricate the castings shown on this drawing.
