Roto Tape Compass | Rotating Tape Measure Beam Compass Alternative Circle Drawing Tool to Draw Arcs (Not 2 inches Short!)
ADVERTISEMENT
Product Details
Use With A Standard Pencil: Don’t fuss with similar drawing compass tools that require you use a custom lead writing utensil. Ours allows you to use any #2 pencil.
Carry In Your Toolbox – Unlike a Beam Compass : Draw circles and arcs of varying radius’ with our retractable circle drawing tool that measures just 5” long when contracted.
Use It For Variable Straight Edges Too: Just flip it over and our measuring tape compass becomes a straight edge tool. Mark your desired distance from an edge with ease.
Metric And Imperial Measurements Up to 6ft Long: Unless you need a circle drawn with a diameter larger than 12 feet, Rocksteel’s rotating tape measure will get the job done.
Measurement NOT OFF by 2 inches: The tape measure measures the distance from the center point where the pin is placed to where the pencil is. Some users are thinking the accuracy is off because the tape starts at ~ 2.5" rather than 0, it is inaccurate. However, that is the distance between pencil & center when the tape is fully retracted. See Image #2 for clarification.
Best Review
Customers find the tape measure works well and makes perfect circles, particularly useful for model train layouts. However, the build quality receives negative feedback, with customers noting it's made of cheap plastic that doesn't hold up well. Moreover, the pin quality is problematic, with several customers reporting missing pins, and the size is criticized for being too small. Additionally, customers disagree on the ease of use and accuracy of measurements.AI Generated from the text of customer reviews
