ALVIN Parallel Gilder Professional Rolling Ruler 10" Model 295 Drafting and Architecture Tool for Students, Hobbyists, and Professionals, Ideal For Drawing Parallel Lines, Circles and Arcs - 10 Inches

For work, I used to draw a lot on a drawing board with a "T" square. The drawings were then copied in a blueprint machine and mailed. Now however, since most people send small drawings via email, the rolling ruler comes into play. I bought and used some cheap rolling rulers and always felt they were pretty much a joke. The wheels were plastic and slid on the paper, which made them non-functioning as a rolling ruler. After breaking the last one (the plastic is very fragile) I decided to splurge, and buy this more expensive ruler. This is a nice little desk-top tool. The rubber "O" rings which are used as "tires" actually make the tool functional. I am very pleased with this tool, and wish I would have spent the extra money years ago. I don't know if the plastic is any more durable? We'll see?

This is a must for people that still like to draw by hand! Small enough not to lose the parallel lines quickly. I own four.

I don’t use many rulers or stencils while drawing but for me this glider was worth the investment. This glider is very versatile; in fact one of my favorite unconventional uses for it is being able to easily hold it up and check the proportions and angles of what I’m drawing. I also like that the glider has holes drilled in it so that you can easily mark measurements. The metal wheels are well made; and still roll straight even after getting bashed around in my bag. The shipping for this item was fast, and it was well packaged. Charles

I think that the 14" version of this tool is really great for my purposes. I am in landscape architecture and often work with very large documents so the added length is crucial. However, it is clear that there is noticeably more wiggle room in the wheel of this glider than in my friends 10" version of this glider . Although it still functions very well and Alvin gliders are by far the best, there is less than a mm of extra space between the wheel axel and the channel it sits in and it causes some minor drifting when you handle it. I am still happy with the purchase but can say with confidence that it is not as perfectly parallel as the 10" which I first used and inspired me to buy this one.

I was recommended this tool while I was in art school. It is a fantastic little ruler allowing you to easily create straight lines without realigning the ruler on the page. The varying sizes make it easy to find the size that fits best for your preferences, and the transparent plastic allow you to properly see where you are placing your ruler. I say there aren't any cons to this product save for, if you are using it on a surface that doesn't allow both wheels to roll, then you are going to be using the tool like any other ruler.

I make a mechanical drawing for almost everything I build in my workshop. I've not yet mastered any CAD drafting program. By the time I study the stuff enough to use it, I can have cranked out many, many drawings by hand. I have been looking for the parallel glider for some time and am now glad I made the investment. It saves much time in drawing parallel lines. So far the rubber wheels are gripping the paper and not sliding. I don't know if they will eventually harden. If they do I suspect that I might be able to replace them with O-rings. Anyway, it's a very handy drafting tool and I'm glad I bought it.

It is okay, but it does not work as well as the one I had 40 years ago. It would maintain parallel lines with ease. This one requires more care and a special touch. Be prepared to double-check a lot of lines during the course of making a simple technical drawing.

This is a must for anybody from the old school who still does do some drafting on paper without totally relying on your computer's AutoCad. Over time I had all kinds of parallel gliders - some cheaper, and some much more expensive. Most of them either didn't move accurately or their brittle plastic just broke apart or provided an uneven drawing line. This one here is exceptional in quality, durability and easy, yet accurate movement. The size is just perfect for also throwing it in your briefcase for performing some field work.

This was expensive but worth it - it is well made and extremely sturdy, and has already been used many times for drawing parallel lines and measuring angles for handwriting practice. I am glad I bought it.
