Without the collar, the mast's weight and side load can be concentrated through the 3\/8-24 stud, creating leverage that can bend the stud. The collar bridges that mechanical mismatch so the mast base is supported at its shoulder instead of asking the threaded stud to carry the bending load.\u003c\/p\u003e\u003ch2\u003eWhen the collar is mandatory\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCHA CFM-34 HD + CHA SPIKE MOUNT:\u003c\/strong\u003e the CHA 34HD COLLAR is mandatory.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCHA CFM-34 HD + CHA SURVEYOR-A:\u003c\/strong\u003e the collar is not required because the SURVEYOR-A bearing surface supports the mast's stainless-steel base shoulder directly.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCHA CFM-34 HD + CHA PORTA-MOUNT:\u003c\/strong\u003e use the complete CHA 34HD REDUCER KIT.
