Tacro - Beam Compass No. 4211
Beam Compass No. 4211
Draw precise circles up to 13 inches with lightweight aluminum beam
Precision at scale requires different tools than desk-sized work. Tacro's Beam Compass handles circles up to 26 inches in diameter using a 13-inch anodized aluminum beam that stays rigid without the weight that causes hand fatigue during careful inking. Thumbscrew adjustments lock the compass head exactly where you need it, maintaining that radius through multiple rotations without drift.
The interchangeable head accepts standard pencils or technical pens, adapting to whatever medium your drawing requires. Divider points serve double duty: use them for transferring measurements or securing the compass center without punching through your paper. Anodized aluminum construction resists wear at contact points where cheaper materials would develop play and compromise accuracy.
Tacro includes spare parts and extra leads so you're not hunting for replacements mid-project. When 26-inch circles aren't enough, add the 24-inch or 36-inch extension beams sold separately to scale up to truly large-format work. Architectural renderers, technical illustrators, and anyone drafting precise circular elements beyond standard compass range will appreciate the combination of reach, stability, and repeatable accuracy this beam compass delivers.
