Description
Technical Overview
The 3 Hole Joining Strip – 40 Series functions as a structural hardware component designed to establish secure inline connections. Technicians actively deploy this specific aluminium strip to form a continuous physical link along the linear lengths of adjacent modular structural profiles. First, you place the hardware component directly inside or against the open extrusion tracks. Then, you secure the unit into position by utilizing standard fastening hardware. Consequently, the strip delivers critical structural alignment across the profile interface. It simultaneously provides cross-sectional joint reinforcement for the combined framework. Furthermore, this direct mounting method allows engineering teams to safely construct extended linear spans.
Applications
Assembly teams regularly utilize this three-hole joining strip when they construct extended machine frames, long linear rail guides, and large-scale modular enclosures. These builders typically deploy the metal hardware alongside standard 40 Series structural framing profiles to extend overall profile track lengths. By implementing this method, teams completely remove any requirement for specialised machining services or custom welding. Additionally, the component performs exceptionally well when you must join linear extrusions for industrial partitioning frameworks. Because the strip ensures a completely flush interface across adjacent linear sections, the compact profile delivers a clean, unobtrusive finish across the entire framing system.

Maker Store Tips and Tricks
-
Ensure the strip sits flush within the extrusion tracking channel before executing the final torque procedure on the fastening hardware.
-
Align the adjacent extrusion profiles perfectly true along their linear axes prior to tightening the mounting hardware.
-
Periodically verify the tightness of all assembly fasteners in frameworks exposed to continuous physical vibration.
What makes T-Slots such an easy assembly task?
Building frames out of T-Slot extrusions is easy because they eliminate the need for specialized tools or welding, simplifying the assembly process. Building frames using T-Slot Linear Rail will require;
- 40 Series T-Slot Extrusions: These are the main structural components, usually made of aluminium, with slots along their lengths that allow you to easily connect various parts and accessories.
- 40 Series Brackets and Connectors: These are specialized components designed to fit into the T-Slot extrusions and secure them together at various angles. They include corner brackets, T-nuts, L-shaped brackets, and other connectors.
- Fasteners: Bolts, screws, and nuts are required to attach the brackets and connectors to the T-Slot extrusions securely.
- Tools: Basic hand tools like 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.
