Door pair makers are an effective way to quickly turn two single entranceways into a double, helping to create a more versatile, open-plan living between adjoining rooms. These simple strips of wood can be fixed along one edge to create a lip that allows one side to slot into the other, and can be fitted on both the left or right side for total flexibility. Suitable for interior use, there is a choice of materials available to best match the entryways being fitted.
