As advertised but price gougingReview by
I bent the wrench that came with my Night rail. This replacement worked as advertised.

The price is ridiculous! ($25 at time of review). If you need this wrench, you already have the rail. No need to ding the potentially "loyal" customer who needs your proprietary wrench. Maybe $5 replacement fee would be reasonable, if that. Both Rainier and Fortis did not return my emails regarding this issue. Instead of waiting another week, I purchased the wrench.
