Must-have for DIY enthusiasts

If you work with aluminum profiles often, keep a box of these handy. The elastic fastener feature saves so much time during disassembly and reassembly of prototypes.

Excellent for modular shelving

I used these to build a custom shelving unit in my garage. The built-in connector design keeps the joints clean and hidden. Very satisfied with the durability of the 304 steel.

Good quality but tight fit on 20mm

Overall great product. They work flawlessly on the 30 and 40 profiles. On the 20mm series, the fit is a bit tighter than expected, requiring a little more force to snap in, but they hold very securely once installed.

Perfect fit for my workshop frames

These butterfly buckles are exactly what I needed for my 40-series aluminum profile project. The stainless steel feels robust and the elastic mechanism makes assembly incredibly fast without needing extra tools.

Fast shipping and great value

Arrived earlier than expected. The packaging was secure, and all 10 pieces were in perfect condition. These are much cheaper than buying individual connectors at local hardware stores.

Solid construction

The metal thickness is impressive. I was worried they might bend under pressure, but they seem very rigid. Deducting one star only because the instructions were purely graphical and a bit unclear initially.

5 FAQ

Q: What is the maximum load capacity for a single connector?

A: While specific load limits depend on the profile structure and orientation, a single connector is rated for medium-duty structural support. For heavy loads, we recommend using multiple connectors per joint.

Q: Is this pack mixed sizes or just one size?

A: This specific listing is for a universal design that fits 20, 30, 40, and 45 series profiles. All 10 pieces in the pack are identical and compatible with all listed sizes.

Q: Are these compatible with Misumi standard profiles?

A: Yes, these fasteners are designed to meet National and European standards, which generally align with Misumi 20, 30, 40, and 45 series profiles.

Q: Can these be used outdoors in rainy conditions?

A: Absolutely. Since they are made from 304 Stainless Steel, they offer high resistance to rust and corrosion, making them suitable for outdoor applications.

Q: Do I need any special tools to install these?

A: No special tools are required. The elastic fastener design allows for tool-free installation; you simply press the buckle into the profile slot until it clicks.
