Does anyone make carpet edging that will work with an inside curve?
The radius of the curve is two feet (60 cm). The total curve is 90
degrees.

Thank you in advance for all replies.

Metal trim?

Never used this product* but have cut pieces for a radius using
regular metal trim.

"CTC Trims and Transitions can easily be modified and installed in a
radius or curve using the following directions as a guide.

Using a tin snips or other appropriate tool, cut the notches out of
perforations in leg. The number of open holes required is dependent on
the size of the radius. The more perforations that are cut the more
bendable the product becomes. (If bending the CTC Joint, you will need
to cut the leg on both sides)

Then slowly bend the CTC Trim into the desired arc. CTC Transitions
can be shaped for inside or outside radiuses We strongly suggest the
use of a template to pre-shape transitions strips prior to
installation. This will prevent "kinking" of materials. A template can
be created out of any sturdy sheet material such as plywood or
masonite."
