Please could you advise me which slot and lock connectors I would need to make a frame similar to GPL-092.
To make this type of frame from slot and lock, you would need ‘Two Way Angled Slot and Lock’ connectors. This is the connector on the far right of the small photos underneath the main picture on the page. You can select this connector from the drop down menu.
I hope this is helpful. If you need any further assistance please don’t hesitate to ask.
