Description
Technical Overview
Engineers intentionally designed the Pivot Arm – 40 Series to create adjustable angled connections between aluminium extrusions. Mechanically, this external hardware component features a distinct extended arm profile. Because of this specific geometry, the component actively provides an enlarged clearance area to facilitate smooth pivot rotation without interfering with adjacent structures. Furthermore, manufacturers build the arm from aluminium and finish it with a clear anodised coating. This allows builders to mount the hardware directly onto a profile T-slot or integrate it seamlessly with an alignment nub. Consequently, the component integrates cleanly into modular framing systems to establish rigid structural connections without requiring any prior machining services.
Applications
Accordingly, builders typically utilize this pivot arm within modular structural frameworks, automation equipment, and custom mechanical assemblies. It functions dynamically as an external connection joint, which allows operators to align and lock two separate profiles at specific angles. Therefore, the component ensures reliable geometric stability across variable angle configurations. Specifically, engineers engineered this hardware for seamless integration with 40 Series T-Slot aluminium linear extrusion profiles. It delivers excellent versatility for framing projects that require frequent reconfiguration because the hardware permits rapid repositioning and complete reuse across different assembly layouts.

Maker Store Tips and Tricks
-
Ensure the pivot arm bolt is sufficiently loosened before adjusting the frame angle to prevent surface wear on the anodised coating.
-
When high rotational precision is required, pair the arm with a locating nub to prevent profile twisting during tightening.
-
Note that this hardware is sized exclusively for 40 Series profiles; for 20 Series V-Slot extrusions, utilize standard 20 Series hardware variants instead.
What makes T-Slots such an easy assembly task?
Constructing frames from T-Slot extrusions is straightforward as they eliminate the need for specialized tools or welding, thereby simplifying the assembly process. To build frames using T-Slot Linear Rail, you will require:
- 40 Series T-Slot Extrusions: These form the main structural components, usually crafted from aluminium, with slots along their lengths for easy connection of various parts and accessories. Additionally, their robustness ensures they hold up well over time.
- 40 Series Brackets and Connectors: These specialized components fit snugly into the T-Slot extrusions, securing them together at various angles. The range includes corner brackets, T-nuts, L-shaped brackets, and other connectors. Besides, they are easy to install and adjust as needed.
- Fasteners: Utilize Bolts, screws, and nuts to securely attach the brackets and connectors to the T-Slot extrusions. Furthermore, their variety allows for flexible assembly solutions.
- Tools: Basic hand tools such as wrenches, Allen keys (hex keys), and screwdrivers are necessary for assembly. Additionally, a saw may be needed to cut the T-Slot extrusions to your desired lengths.
