A very nice tool for the price.
For the price, this is a very nice square / line marker. After reading some of the reviews, it’s easy to see why some have the problem of the side rail not being perfectly inline with the main body. There is a small amount of play in the connection before it’s tightened. If the screws are put in loosely and then you put it on a known flat surface – you should then be able to tighten the screws and the two pieces will be aligned. After tightening the screws, the connection seems solid, stable and aligned.

Very accurate, just needs a shorter right angle leg.
This tool is designed for 2â lumber. I didnât pay attention when I ordered and I would prefer this same tool designed for 3/4â lumber. One right angle is attached with screws, I will check and see if a shorter leg is availableThe tool works perfectly for drawing lines. It is a good tool at a good price.All my work is small pieces as I build mostly Tiffany Lamps.

Handy tool
The Amazon package landed on my porch with a soft thud, a small victory after weeks of scrolling for the perfect tool. Inside was my $15.99 Woodworking Square Ruler, a sleek, multi-angle scribing tool promising precision for my carpentry projects. As a weekend woodworker crafting shelves and frames in my cluttered garage, I needed something affordable yet reliable to nail those tricky 22.5- to 90-degree angles. The ruler, with its aluminum body and angle pin, seemed like the answer.I tore open the package, admiring the rulerâs laser-etched markings, crisp and clear against the brushed metal. The angle pin, a sliding guide for quick angle sets, felt sturdy, and the compact 8-inch length fit neatly in my tool belt. Eager to test it, I grabbed a cedar plank for a picture frame I was building for my wifeâs birthday. Setting the ruler to 45 degrees, I locked the pin and scribed a line. The cut, made with my miter saw, was spot-on, the corners joining seamlessly. I grinned, feeling like a pro.Next, I tackled a trickier 22.5-degree angle for a decorative shelf edge. The rulerâs precision markings made it easy to set, and the non-slip base held firm as I marked the wood. The angle pin was a game-changer, letting me transfer measurements without second-guessing. Sawdust flew as I cut, and the pieces aligned perfectly, giving the shelf a modern, geometric flair. For $15.99, this tool was punching above its weight.But it wasnât flawless. On a complex octagon-shaped coasters project, the rulerâs small size made long lines cumbersome, requiring multiple setups. The angle pin occasionally loosened under pressure, forcing me to double-check settings. And while the aluminum was durable, I noticed faint scratches after brushing against a nail in my workbench. A quick polish fixed it, but I wished for a protective case.By evening, Iâd finished the frame and shelf, both boasting clean, professional angles. I stepped back, hands dusty, admiring my work under the garage lights. The ruler had saved me time and frustration, its affordability belying its precision. Later, I used it to scribe lines for a staircase repair, its versatility shining in construction tasks beyond woodworking.For $15.99, the Woodworking Square Ruler was a steal, transforming my garage projects with its accuracy and ease. It wasnât perfect for large-scale work, but for a hobbyist like me, it was a trusty companion. As I hung the frame, my wifeâs smile confirmed it: this budget tool had helped me craft something special.Word Count: 450

Bad screws.
This is made up of two pieces that screw together. It’s made of aluminum and is fairly soft. The two screws that hold it together are allen keys. It comes with a little allen key to put it together. Yeah they don’t match. The provided key and the screws. No problem I have several sets of allen keys, metric and standard. I don’t have any keys that fit the screw heads. Kind of but not really. Not a big deal close enough will work for this. Unfortunately there is a lot of slop, as the screws don’t tighten down. the two pieces move around making it difficult to get your line correct when going around corners. Which is the whole purpose of this device. I am sure with the correct/different screws it will work. I assume the slop is to be able to adjust the alignment. I am not going the the store to buy different screws for this thing.
