The belt diameter should generally match or be very slightly larger than the groove width to ensure a snug fit. For example, a 3mm groove typically works best with a 3mm round belt. When in doubt, size up by 0.5mm for a tighter grip.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eCan I join the belt ends to make a continuous loop?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eYes. PU round belts are typically joined by heat-welding or using a belt connector clip.
