BBL 100mm Ball Hinge – 304 Stainless Steel | 3mm | Black
When the door is heavy, the traffic is high, or the environment is demanding, you need a hinge that won't flex under pressure. The BBL 100mm 3mm Ball Hinge is the heavy-duty choice — built with a thicker 3mm leaf for superior rigidity, load-bearing capacity, and long-term reliability on solid timber doors, exterior gates, and high-use applications.
Crafted from 304 stainless steel with a sleek black finish, it combines industrial-grade durability with a clean, modern aesthetic suited to both residential and light commercial applications.

Best Suited For

Frequently Asked Questions
How many pairs of hinges do I need per door?
For standard doors up to 2032mm high, 2 pairs are typically sufficient. For taller or heavier doors — such as solid hardwood or fire doors — 3 pairs are recommended to distribute the load and ensure smooth operation.
Are these hinges suitable for coastal installations?
Yes. The 304 stainless steel construction makes these hinges highly resistant to corrosion, making them an excellent choice for coastal homes and high-humidity environments where standard steel hinges would deteriorate quickly.
What is the difference between 2mm and 3mm hinges?
The 3mm leaf thickness provides greater rigidity and load-bearing capacity compared to a 2mm hinge. For heavy solid timber doors, exterior gates, or high-traffic applications, the 3mm hinge is recommended. For lighter interior doors, the 2mm version (BBF304-20BL) offers a slimmer profile that is sufficient for the load.
Can these hinges be used on exterior doors and gates?
Yes. The 304 stainless steel construction and black finish are designed to withstand exterior conditions, including rain and sun exposure. They are suitable for exterior doors, garden gates, shed doors, and other outdoor applications.
