The 6 hole - wide 2x4 slotted inside corner bracket is an external fastening method that creates a 90 degree connection. One side of the bracket has two adjacent holes and the second side has four holes comprised of two rows and two columns. The two adjacent holes are slotted, allowing for a larger degree in adjustability between connecting profiles. This fastener requires no machining services and can provide infinite positioning along the profile T-slot, allowing a large degree of adjustability. It engages the 2-degree drop-lock feature when the assembly bolts are tightened to the required torque and can also be repositioned and reused. The suggested mounting hardware can be found on the "Suggested Hardware" tab.

The 3 way - rounded corner connector is an external fastening method that is typically used to create a curved corner connection between quarter round profiles. It is a heavy-duty connection that is simple to use and provides a finished appearance while the rounded corner prevents sharp edges. The 3 way - rounded corner connector requires an end tap machining service on the mating profiles. The suggested hardware can be found on the "Suggested Hardware" tab.

The 4 hole - wide gusseted inside corner bracket is a strong, external fastening method that creates a 90 degree connection. There are two adjacent holes on each side of the bracket. It requires no machining services and can provide infinite positioning along the profile T-slot, allowing a large degree of adjustability. The shape of the gusset provides extra material, strengthening the connection. The 4 hole - wide gusseted inside corner bracket engages the 2-degree drop-lock feature when the assembly bolts are tightened to the required torque. It is a fastening method that can be repositioned and reused. The suggested mounting hardware can be found on the "Suggested Hardware" tab.
