💡 How does a heavy duty draft compass stay accurate while transferring large layout dimensions?
The adjustable tension design locks your working radius so the legs do not slip when pressing down hard.
- Snap lock mechanism holds precise measurements during repeated swinging motions
- Swivel pivot joints reduce drag so the steel legs glide smooth over rough lumber
- Rigid zinc alloy shell absorbs impact drops so calibration never shifts sideways
- Dual leg slots accept standard graphite leads or plastic ink ballsinks for permanent blueprints
