As of September 20, 2023, it has been confirmed that modification is necessary. The mounting holes on the plate are threaded, which can conflict with the threaded holes on some iOptron piers when using GEM45 hardware. Successful adaptation requires drilling out the threads on the plate's mounting holes and countersinking them to allow mounting bolts to sit flush.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWhat is the iOptron Pier Top Plate for?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThe iOptron Pier Top Plate is a mechanical adapter designed to connect specific iOptron equatorial mount heads, primarily the \u003cstrong\u003eCEM60\u003c\/strong\u003e and \u003cstrong\u003eCEM70\u003c\/strong\u003e, to an iOptron tri-pier or permanent pier.
