Identification and sourcing
Thresholds
Centennial Glass can help identify and source this type of hardware when it is a practical match for the complete window, door or glass system. Availability varies by manufacturer, dimensions, handing and installation requirements. Send photos of the full assembly and the original part so we can assess the request before recommending a replacement.

Frequently asked questions
Thresholds identification
What information helps Centennial identify thresholds?
Send photographs of the complete assembly and the component from several angles, then include manufacturer markings and the measurements listed on this page. Mounting preparation, handing and dimensions may determine compatibility.
Can this hardware be replaced by appearance alone?
Usually not. Similar-looking components can differ in dimensions, load rating, handing, preparation and compatibility. Centennial reviews the complete opening before recommending a match or substitution.
Can Centennial install or repair this hardware?
Service depends on the hardware and the condition of the complete assembly. Send project photos or arrange an assessment so the team can determine the appropriate parts and repair approach.
