When it comes to metalworking, welding and fabrication, precision matters — and holding workpieces securely at just the right angle can make all the difference between a perfect joint and a frustrating re-do. That’s where the Eclipse Magnetics 90° Inside/Outside Clamp Large comes in: a simple, powerful magnetic tool that transforms how you position and secure steel components during preparation and welding.
What Is a 90° Inside/Outside Clamp?
The 90° Inside/Outside Clamp is a magnetic welding aid designed to hold internal and external joint surfaces at fixed angles — specifically 30°, 60°, and 90°. This flexibility makes it ideal for setting up sheet metal, angle steel, tubes and flat stock before welding or assembly.
Unlike traditional clamps that rely on screws or bolts, this product uses strong permanent magnets that grip ferrous materials instantly and hold them securely in place during tack welding and alignment operations.
Why Use This Magnetic Clamp?
🔩 Fast, Accurate Positioning
Magnetic force means parts are held instantly and securely without fiddly adjustments. This saves time and ensures consistent alignment every time.
🔧 Versatile Angle Clamping
Whether you’re working on inside corners or external joints, the independent magnetic faces let you clamp from both sides — extremely useful where space is tight or traditional clamps can’t reach.
⚡ Simple and Efficient Setup
With linking holes built in, multiple clamps can be joined together for larger jigs or fixturing systems. And when the job is done, a hex hole lets you leverage the tool off easily without wrestling metal parts apart.
🛠️ Strong and Reliable Hold
Despite its compact size, this clamp offers up to 18 kg pull force, giving confidence that your workpieces won’t shift while you prepare to weld.
Ideal Applications
This magnetic clamp is a favourite tool in workshops and fabrication bays for tasks such as:
-
Holding sheet metal and steel tubes at precise internal or external angles
-
Supporting angle iron and flat stock during tack welding
-
Aligning framework pieces before permanent welds
-
Securing components for rapid repositioning during production jigs
Tips for Best Use
-
Use the clamp during tack welding and setup only; remove it before completing the full weld to avoid exposure to high temperatures that can weaken magnetic strength.
-
Keep metal contact surfaces clean and free from heavy rust or dirt — this ensures maximum holding force.
Conclusion
The Eclipse Magnetics 90° Inside/Outside Clamp Large is a deceptively simple tool with high impact. It speeds up fabrication work, improves accuracy and makes welding setups easier — especially when working with complex angles or limited access. For shops and hobbyists alike, it’s a practical, cost-effective addition to the toolkit that pays dividends in efficiency and quality.
