Kapro Prolaser T-Laser T-Square

This is a handy little laser about the size of a tape measure and even has a belt clip. It clips over the edge of drywall, plywood or any substrate 1/4″ to 5/8″ thick. It automatically turns on when attached to the material. You can also just set it down on the surface and turn it on manually. When using it by just setting it on the surface and not clipping it, the laser light is not as prominent and there is a several inch gap in the light from the edge of the unit to where the light becomes visible. It hold tight though when clipped to the material.

This is the best thing since buttered bread. The Prolaser makes the job easier and helps it to move alone much faster. It gives you confidence that your measurements are correct and the placement of your screw or knife are where they need to be. It is perfect to produce a straight line and to square off the cut. If you are working with sheet-rock or plywood this little tool will make it much easier and precise. The design allows the Prolaser to clip onto the plywood or sheet-rock which makes it very easy to use. If you work with plywood or sheet-rock you can’t do without this tool.

This T- Laser T- Square is very useful. I used it to cut a straight line on vinyl and worked perfectly. This tool is especially handy when cutting wall board because it takes less effort than chalking a line. Just clip it to the board and follow the line. When you clip it, the laser illuminates. I like that it has a switch to turn it on when you don’t use the clip. The laser light is very bright so it can be used in well lit environment.

It’s ergonomic and quite easy to grip with its cutouts and rubber grip. I would imagine this also helps in the case of dropping. However, I have dropped a simple laser tool similar to these one before and it did not fare too well, even form 5/6 feet high. It’s pretty cool how it automatically powers of from the pressure switch. You can also manually turn it on if needed. The center of the laser is 1-3/4″ from the bottom and goes downward. It’ll latch securely onto anything 5/8″ thick or less. Now, perhaps it’s just a dud/ bad batch, but mine is nearly off by 1/4″ at 4 feet! I checked it on three different areas to be sure. If you take away all the great things about this tool that were mentioned earlier, it now becomes entirely useless. It would also be great if they made the sides perfectly flat so that you could use it as a perfect 90 degree box from all sides. The belt clip is a nice feature, and the fact that it’s the size of a tape makes for easy operation, even in tight spaces.

The Kapro 893 Prolaser T-Laser T-Square is the size of a standard tape measure that can clip on to your belt. The Case is an ergonomically molded bi-material with a rubber overlay. The Kapro 893 allows carpenters and drywall contractors to mark exact 90° lines over wood or drywall for free-form cutting. The 90 degree highly visible laser beam has a range of 10 feet and is powered by three AAA batteries. This tool replaces the need of traditional tools that require repeat measuring and marking. Kapro supports this product with a 12 month limited warranty.

The idea behind this Prolaser T-Laser T-Square is a good one: clip it onto the edge of drywall boards, instead of using a metal T-square or chalk line. It is roughly the same size as a Stanley 25 ft tape measure and fits nicely in a tool pouch. In use it projects a red laser line on the board for free-hand cuts. In practice I don’t think I would use it (at least on a regular basis) across the 4′ width of the board because using a drywall T-square is just so much faster. Along the length it is a bit faster than snapping a chalk line but it has its limitations. To use the T-Laser, I first made a cutting mark on each end of the board in pencil. Then slide the unit onto the board and the built in switch activates the laser while the metal clip holds it firmly in place. Next simply use a utility knife to score along the red line. However, as I said, it does have its limitations. First, unless the board is absolutely flat the laser will not always project a clean line the entire length, especially on 12 ft boards. Secondly, the line gets washed out in bright light and I was unable to see it past the first few feet. Outside I found it to be useless.It still may be a handy tool as long as the ambient light is not overly bright and you would rather not deal with a chalk line. That’s when I’ll use it. Other than that I think it has limited usefulness. It also has a manual on/off switch and can be used just by sitting it on the surface, not clipping onto the board.

It works as advertised, but has specific uses. While it seems pretty accurate, I think that it is marginally better that a straight edge and a chalk line. The issue with using it in a vertical position, is that it is only as accurate as the bubble levels. When I used it on a wall, I lined it up with a 48″ level first.I have used this to build an 8′ row of supports for lumber storage. I used a straight piece of lumber first to line up the frame, and checked it with the laser square.This is a nice-to-have tool, but it will not replace a good 4′ level and accurate speed square.

This is a tool looking to solve a problem that doesn’t exist. First and foremost, it does what it says it will do, it clips on to drywall and projects a straight line. The problem is, what are you going to do with that straight line? If you trace it or cut on it… a T-Square would have bee a much better tool to use because you can drag your pencil or blade along it. If you put this on the floor or ceiling to project a straight line… how are you going to secure or level it? A laser level would have done that batter. It fails to do a laser levels job, and it fails to do a T-Squares job… I’m struggling to come up with a reason to give it shelf space in an already crowded workshop.

The Kapro Prolaser T-Laser T-Square model 893 looks and feels similar to a pull-out tape measure but, it’s lighter in weight and has and ergonometric grip that makes it unique and comfortable to hold. Cutting sheetrock is simplified because I no longer have to mark cutting lines on the drywall surface. The T-Laser/T-Square slips over the square edge of the rock about 1-1/2 inches and projects a sharp, highly visible laser beam over the cutting line at a 90 degree angle to the edge. The laser beam remains clear and sharp at 10 feet for longer sheets of drywall. The Laser Square works the same for shelf boards or plywood up to 7/8-inch thickness. There is a spring clip in the opening of the Laser Square that turns on the laser beam and holds the unit firmly in place while working. The belt clip keeps it handy when needed and I don’t have to search through my tool pouch to find it. There is a manual power switch on the side that allows me to use the laser beam on surfaces where I can’t clip the unit in place. I can think of a lot of uses for the T-Laser/T-Square and feel certain you can think of more.
