## Description

Product Description Rotape Compass (3-1/2 Inch to 6 Feet Capacity) From the Manufacturer Big Horn's 19641 is the original Rotape Beam Compass from Brat Manuf. This marking device combines a measuring tape and pencil scribe in one pocket size tool. It makes a radius from 3-1/2-Inches to 6-feet. It also can be used to mark straight and parallel lines, arcs, and circles. Use on wood, steel, concrete, drywall, fabric, chalkboard, and more. Includes centering pin, collett and pencil lead. Replaces the standard beam compass and trammel point set. Made in USA.

Review: A must have for ALL diyr's - Better than I expected and it works perfectly. For years I have attempted drawing radius curves onto my projects using the old string method. I am so glad that I finally jumped to the "other" side. This pro pass is accurate, well built and offers perfectly drawn lines. It does not matter if they are straight or radius. It is very easy to use, comes with everything you need and will end the frustration in the shop. It can be used for many things around the house as well.
Review: Great investment for someone that has many uses for it. - The product overall is great. Not easy to use for some, I can see why the reviews. It takes coordination and practice. I think if it was able to use a regular pencil or pen instead of lead replacements that I’ll have to order from staples or somewhere, I think that it would be the perfect tool for any amateur craftsman or seamstress. I have rigged up a ink pen and ground down a pencil to fit. I still use the brass fitting and lead provided, please note: tighten it so it will not slip while using and don’t press too hard! For me this was a great investment and was extremely excited to use it and will have many uses the years to come:)

### ⭐⭐⭐⭐⭐ Great investment for someone that has many uses for it.

### ⭐⭐⭐⭐ Handy tool but lead slips
*by A***E on April 3, 2019*

I needed to cut a perfect 18” diameter out of wediboard for a mosaic substrate. This tool worked very for my purposes and I am glad I have it now, for cutting any sizes in the future. The reason I gave it 4 stars is I continually had to stop and tighten up the piece of lead as it kept slipping. Also, other reviews have mentioned this specific size of lead is difficult to find once you have run out of the lead that is sent with the set, and only this size lead will fit. So I anticipate possible trouble replacing the lead in the future.
