HOP magnetic gauge for measuring firewood.

Heavy duty fiberglass 16 inch length gauge.  The gauge has a magnetic base with a pulling force of 100 pounds.  The gauge can therefore be placed anywhere on the chain saw blade on the left or on the right depending on the situation.
 
 It comes with a metal hook that allows it to be worn at the waist and to be used easily and effortlessly.
 
 The use of this gauge improves the ergonomics of cutting firewood.  It significantly reduces back flexions and body movements.
 
Firewood cut to  the right length is easier to pile and the volume can be more easily appreciated and accurate.
