What happens here

The presenter demonstrates the Versa-Lok standard unit, emphasizing its solid concrete construction. Unlike hollow blocks, the Versa-Lok unit is entirely solid, which prevents it from busting apart easily, for example, when struck by a hammer. The block's perfectly flat top and bottom surfaces are highlighted as crucial for stability, as there are no 'nubs' or 'lips' that could crack or degrade over time, a common issue with other block types. The key to Versa-Lok's connection method is its pin system. Pins are dropped into four pinholes on the top of a block, and these pins align with slots on the bottom of the block above it. This creates a secure, spiked connection that prevents forward or backward movement, even with ground or frost movement, ensuring the wall's integrity. The presenter demonstrates how to slide blocks into place before pinning them, ensuring a tight fit and a solid level unit.

Goal: Demonstrate the solid nature of Versa-Lok blocks and their unique pin-based connection system.

a little difficult to hear so what we have here is a versalock standard unit one of the things I want to show you about this block it's a solid unit you do this with a hollow block and that sucker is going to bust apart on you solid here solid here you'll notice perfectly flat perfectly flat okay why is that important you don't see any Nubs you don't see any limps so the question you probably should have is how do these things go together that's an important feature with these blocks and one of the reasons why I like them okay all right so the way that these blocks connect this is what I love about them is pins and so what we do we got four pin holes we have slots in the bottom all you literally do is drop these pins in and now you've got a connection you've got a block that isn't relying on a little concrete lip to hold it together you've got actually a spike going through one block and hitting into the next block below it which means that when you get Frost movement or ground movement what happens is that Spike sticks you can see this block is not going to move forward or backward I'm not a salesperson for First Lock but my reputation my company rides on it you can see these spikes in here that's how solid of a connection that they make this block can have this much movement it's never going to but it can have that much movement and still be Rock Solid and you know one thing too Stan that that I just want to interject here is a big part of reason why guys like us like you said is is because of the pins you did good about showing there that you definitely want to you know bump it up a little bit but the other good thing that you can do when you're under a construction here is before you pin you always want to try to set your block off oh maybe about a foot or so and then slide it into place so you got where your block is and you're just going to slide it into place and then pin them and the reason for that is if there is any minor we like to use a real technical term called concrete boogers on the top we slide those off and then you got a really nice solid level unit that you're working with so this block can be used both in residential and Commercial applications I it's a little
