Review Detail

This chalk box come with a finely braided line that leave a thinner line than is usual for most chalk boxes.
It comes with a lock that will hold the line, so you can use it without having to touch the line. The lock automatically disengages when you retract the line. This is a nice feature if you can remember to use it. (I can't, old habits die hard)
This box feels light weight, that, to me, means it may not be that durable, but in the years that I've owned it I've yet to break it, despite being dropped off roofs and the other indignities that chalk boxes endure on the job site.
