Excellent crack prevention

I used this on an old stone board that had chipping issues. This strip covers the vulnerable edge completely and seems very durable. Highly recommend for older homes.

Good product, shipping damage

The trim itself is high quality, but mine arrived with a small dent in the corner. It wasn't visible after installation, but better packaging would be appreciated.

Sleek and modern

Transformed my dated windowsills into something modern. The matte silver finish is not too shiny and hides fingerprints well. Great value for the price.

Exactly what I needed

Fit perfectly on my 20mm thick stone board. The pressing line design makes it sit flush without gaps. Will buy more for the kitchen counters.

Good quality, slightly tricky to install

The material feels sturdy and the color matches my hardware perfectly. Installing it required some patience to get the putty level just right, but the result is worth it.

Perfect finish for my renovation

This aluminum trim gave my new windowsills a very professional look. It was easy to cut with a miter saw and the putty embedding held it securely in place. No sharp edges either.

5 FAQ

Q: Will this work on a 1-inch thick marble slab?

A: Yes, as long as the edge thickness does not exceed the internal channel depth of the trim. This profile is designed to accommodate most standard stone board thicknesses up to 25mm.

Q: What type of putty or adhesive do you recommend?

A: We recommend using a standard tile adhesive or a high-strength construction putty compatible with both aluminum and stone materials.

Q: Can this be cut to custom lengths easily?

A: Yes, this aluminum alloy trim can be easily cut to your desired length using a standard hacksaw or a miter saw with a fine-tooth blade.

Q: Does this come in black or gold finishes?

A: Currently, this specific model is only available in Matte Silver. Please check our store for other profiles that may offer different color options.

Q: Is this suitable for outdoor windowsills?

A: Yes, the anodized oxidation treatment provides good resistance to weathering and corrosion, making it suitable for covered outdoor areas.
