When to choose it

The 23D starts at 103 degrees and flexes toward 90 degrees according to the listing. The starting angle describes the unloaded blade. Choose the tool for a recessed right-angle corner and check both faces for clearance near adjoining trim.

The blade is flexible stainless steel with an aluminum mounting and DuraSoft grip. Compare the adjustable nylon tool if the wall opens to an angle that this fixed blade is not intended to finish.
