 Hey everyone, I'm Tom from Morton's On The Move and welcome to Road Gear Reviews. Today, we're taking a look at the X-Chalks from BAL RV Products. Stay tuned. The X-Chalk is a mechanical chalk designed to work with tandem axle trailers. It works by expanding out against the tires and locking them together so they cannot turn. It's designed to work on trailers and RVs and you're typically going to have two of them, one for each side of the trailer. So what you get in the box is one X-Chalk and one three-quarter inch ratchet designed to sit on top of it that controls the contraction and expansion of the chalk. So this chalk is designed to work with tires that are up to 10 inches apart or as close as one and three-eighths inches together. I have seen it be attempted to be used on tires that are really close together before and I'd say that probably two inches is about as close as they can be and still use this functionally. The chalk is relatively lightweight and has this convenient handle that you can easily carry it around with and put it in between your tires with. The chalk is made out of steel but it does have a rust preventative coating on it and although this one's brand new, we have been using ours for over a year and we don't see any rust on the chalk. A neat feature of this is that it is lockable. When they're expanded against the tires, you can put a padlock through these holes on the end and it will prevent this from being rotated and removed from your trailer. As opposed to other chalks out there, this is designed to work with the natural movement of the tires instead of against them and the benefit that that gives you is that it locks the tires 100% in place and they cannot move and what it does for you is it adds a lot of stability to an RV. It prevents forward and backward movement that you could normally get in the tires. Even if you've got them chalked real tight, you're still going to have a little bit of movement in the tires and this completely locks them up and prevents that. That being said, this is not intended to act as a parking brake to keep your RV or trailer from rolling away. It specifically states that in the literature as well. The intended use of these chalks is to place them between your wheels once you've got your trailer level and set up in its appropriate place. Then it will provide all the extra stabilization that you wouldn't have without them. We have found these extremely easy to use. We expand them to the size of our tires and we typically don't have to even move them that much once we've got them set up. We just loosen them up a little bit, take them out of the tires, put them away and then when we're at their next location, we can easily place them back into the tires and tighten them up with only a few cranks and the trailer is locked up and very stable. We've been using these chalks for over a year and they make a noticeable difference. Before we had them, we didn't know what we were missing, but once we've got them, if we forget to put them in, you definitely notice that they're not there. These chalks are easy to use and they feel really well built. They've held up in all the use that we've put them through and they're also made right here in the USA. One drawback to these chalks is that you can see there's a lot of moving parts on here and that poses a bit of a pinch point hazard. If you're cranking these down, all of these are starting to move and if you get your finger in the wrong spot, that could really hurt. There's even a warning for pinch points right on the handle, so you got to be careful when using them. Another thing you want to consider is that the screw in here that actually draws these up and down needs to be kept greased. It comes with some grease on it and that could be a drawback. If you want to throw it in your car, you could get grease on your carpet or something. We put them in the back of our truck so it's not really a problem. Like I said earlier, this extends out to 10 inches, but they do make a model that extends out to 17 inches for wider space tires.
