Highly recommended

Easy to install and very secure. These corner plates make the door frame feel incredibly stable. Will definitely buy again for my next renovation project.

Excellent for professional use

I am a contractor and have used these on several jobs. They provide a solid connection point for miter joints. The aluminum alloy is high grade and does not bend under pressure.

Solid hardware

These fasteners are robust. The sandblasted look is clean and professional. Took off one star because shipping took a little longer than expected, but the product itself is top-notch.

Great thermal insulation

Bought these specifically for the thermal break property to improve energy efficiency in my sunroom. They work great and the installation instructions were clear enough to follow.

Good quality, slightly tight fit

The material feels premium and heavy-duty. Installation was straightforward, though the fit was a bit tight on one of the profiles. Once secured, they hold very well. Good value for the price.

Perfect fit for my window project

These corner codes are exactly what I needed for my aluminum window assembly. The thermal break feature is a nice touch, and the sand code finish matches my frames perfectly. Very sturdy construction.

5 FAQ

Q: How many pieces come in one package?

A: Each package contains 4 corner code plates, which is sufficient for assembling one standard rectangular window or door frame.

Q: Can these be used for exterior doors exposed to rain?

A: Yes, the aluminum alloy material is corrosion-resistant and suitable for exterior applications. However, we recommend ensuring proper sealing around the joint to prevent water ingress into the profile cavity.

Q: Are these compatible with standard 60-series aluminum profiles?

A: Yes, these corner codes are designed to be compatible with most standard 60-series aluminum door and window profiles. Please check your specific profile dimensions before purchase.

Q: Does the sand code finish resist scratching?

A: The sandblasted finish provides good resistance to minor scratches and fingerprints compared to polished surfaces, but like any aluminum finish, it can be scratched by sharp objects or abrasive materials.

Q: What tools are required for installation?

A: You will typically need a drill, appropriate screws (usually included or specified in your profile system), and a screwdriver. A miter saw is required to cut the profiles to size before attaching these plates.
