End connector 40-series

End Connector for 4040 Aluminium Profiles (40 Series) – Die-Cast Aluminium, 13 mm

Build strong, clean and compact connections in your aluminium extrusion projects with this End Connector for 4040 (40 series) aluminium profiles. This connector mounts directly to the end face of a 4040 T-slot profile using a single bolt, and then fastens the assembly to a second profile with two slot bolts and T-slot nuts. The result is a rigid, space-saving joint with a professional finish—ideal for machine frames, guarding, workstations, enclosures, robotics and modular constructions made from T-slot aluminium profiles.

Fast, reliable mounting with standard fasteners

This aluminium profile end connector uses common metric hardware, making it easy to integrate into existing 40 series systems and spare parts kits:

• Connection to the end of the 4040 profile: 1× M8x25 ISO 7380 bolt
• Connection to the second profile (T-slot mounting): 2× M5x16 ISO 4762 bolts + 2× 8-4-M5.40 T-slot nuts

Durable die-cast aluminium – compact and strong

The connector is made from die-cast aluminium and features a 13 mm thick plate, providing a sturdy base for structural connections in modular aluminium profile systems. Die-cast aluminium offers a strong balance of strength, dimensional stability and cost-efficiency for both industrial builds and high-quality DIY projects.
