Regular Straight Orifice Holders
- Orifice drill size replaces part suffix-xx; e.g., part number 4101-65 indicates orifice hood with #65 drill (.035 diameter)
- Gas orifice can be changed from fixed to adjustable by adding optional point (24-041-02)
- To order assemblies with points, add suffix -yyP to part number where yy is the point orifice drill size; e.g. orifice holder 4101-65-74P will have hood witha #65 drill and a point with a #74 drill (.0225 diameter)
- To specify a solid point (no orifice drill), add suffix -00P.
