This comprehensive kit includes 4 different MXL synchronous belts, 2 MXL pulleys, and 2 L-shaped hollow adapter plates to ensure compatibility with virtually any electronic focuser. With all necessary M3 and M4 screws included, you can achieve a rigid, backlash-free connection for repeatable, accurate focusing across every imaging session.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eA Tensioner Pulley System for 0-Backlash Focusing\u003c\/h3\u003e\n\u003cp\u003eStandard belt-drive systems for electronic focusers often suffer from unavoidable belt slack, which introduces backlash and compromises focusing accuracy.
