The Top clamp (patch fitting) M-939 is a hardware component designed to secure frameless glass doors. It accepts glass panels between 8 mm and 12 mm thick and can support door weights of up to 80 kg. The fitting is offered with axial centre‑point distances of either 53 mm or 56 mm to match different frame designs. Its maximum supported door width is 1100 mm, making it suitable for large commercial openings. The body is fabricated from stainless steel grade 304 combined with zinc‑alloy inserts, a composition that industry standards cite for corrosion resistance in indoor and semi‑outdoor environments. A typical hardness for 304 stainless steel in such fittings is around 150 HB, and the material meets the ASTM A240 standard for sheet and plate. Standard tolerances for the axial centre‑point spacing are ±0.2 mm, ensuring alignment with the mounting brackets supplied by most glass‑door manufacturers. The clamp is usually finished with a brushed or polished surface, which is a common aesthetic choice for contemporary architectural hardware. It is widely installed in office towers, shopping malls and public buildings where tempered or toughened glass panels form doors, partitions or façade elements. Importers and distributors serving the architectural hardware and construction sectors are the primary customers for this fitting. The supplier lists flexible trade options, including FOB or CIF shipping and payment by L/C or T/T, while the minimum order quantity must be confirmed directly with Foshan Chunli Lasting Hardware Door Control Manufacturing Co., Ltd.

Before placing an order, verify the supplier’s business licence, the factory address in Foshan and any third‑party audit reports they can provide. Request product drawings, material certificates for stainless steel 304 and zinc alloy, and ask for a sample unit to confirm dimensions and finish. Confirm that the supplier can meet any required certifications such as ISO or CE, even though they are not listed in the public profile.
Logistics for this hardware typically involve a lead time of several weeks, but the exact schedule should be confirmed directly with the supplier. Buyers should discuss Incoterms - FOB from the port of Guangzhou or CIF to the destination port - and align payment terms, which the supplier indicates can be L/C or T/T. Clarify any packaging requirements, such as bulk cartons or individual protective wrapping, to avoid damage during transit.
When importing, arrange for a pre‑shipment inspection based on the ISO 17020 standard to verify dimensions, material composition and surface finish. Request a test report for corrosion resistance and hardness, and ensure that the packing list and certificate of origin are included in the shipping documents. Maintaining these checks will help guarantee that the delivered clamps meet the technical specifications required for commercial glass‑door installations.
