The 2 hole - transition inside corner bracket creates a 90 degree connection between profiles within the same product type (either fractional or metric) but of differing series. It is an external fastening method that requires no machining services. The bracket is flush with the profiles, taking up less space in the overall design. This option can provide infinite positioning along the profile T-slot, allowing for a large degree of adjustability as well as being reconfigurable and reusable.
