Features
Green laser
Ten times brighter than red, so more clearly visible.
Patented reflected laser beam
The laser line travels to the reflector on the other pulley and back again. This shows offset, vertical angle and horizontal angle in one go.
Magnetic
Attaches magnetically to the inner or outer face of any pulley or sprocket; no loose parts to lose.
One person, no training
Align in a few minutes, without training.
Built-in LED light
The switch also operates a flashlight, handy in dark machine housings.
Longer service life
Less vibration and belt noise, longer life of belts and pulleys, and less downtime and energy consumption.
Also for aluminium and stainless steel
On non-magnetic pulleys and sprockets you attach the tool with a clamp.
Applications
V-belts and timing belts
Accurately align pulleys of belt drives.
