This bracket allows you to connect extrusions at right angles to one another. It is suitable for use with PG30 extrusions. They are not as strong as the screw or butt connectors but are fast and easy to use. A 3mm hex drive is required to tighten the set screw.
Of critical importance is that you make sure you have selected the correct type (A or B). Refer to the T-slot primer in the resources section for information on selecting the correct style.
