Sergio, thank you for your interest in our products. Yes, we do have a variety of "screen" block, as we call them, but availability varies a lot by location and some plants do not carry any. Please call the location nearest you, https://www.angelusblock.com/contact.cfm, and ask for what may be available. They can check other locations as well.
Most likely they have your block if you have any questions you can call any of the locations are go on the website
