Question about Sp Connect Universal Phone Clamp SPC+

...square and or round edges?

The Universal Phone Clamp SPC+ is suitable for almost all smartphones, regardless of brand, model, size or thickness - the product is designed as a universal mount. According to the manufacturer, the mount fits smartphones with a width between 58 and 85 mm (2.28-3.35 inches) and a maximum thickness of 12 mm (0.47 inches). This allows you to securely attach both thin and thick, large and small devices to the handlebars as long as they are within these dimensions. The mount is rotatable and can be adjusted without tools. For very large or particularly thick devices (e.g. with a thick protective cover), we recommend taking a look at the exact dimensions of your smartphone to ensure compatibility.
