Outside door thresholds
Traditional outside door thresholds are installed on site under wood, plastic and aluminium frames. Thanks to the sheer range of sizes available, we have the perfect outside door threshold for every frame. If desired, jambs can be delivered separately. Alternatively, we can mount the jambs under the frame struts.
Information about thresholds (Kumax) that are mounted under frame struts in the joinery is available under Window frame industry.
