Bought for pelican trailblazer 10 foot kayak. This lock is for a 34;touring kayak34; which explains why I might have had trouble. I was unable to get this to work with my intended goal of securing my kayak to a post. It probably works fine on other boats but the nose and tail of the trailblazer was too round/wide to get a good tight grip. even with considerable effort to get the lock tightened, I found that I could just slip one end off of the boat and then the whole thing was free. Be aware of the geometry of your boat before you buy.

Just bought two of these, and I can't set any combination other than 0000, which really defeats the purpose of the lock. The spindle on each lock won't rotate properly, no matter what I do to the number wheels. For fifty bucks apiece, these things should work. Don't buy unless you're looking for frustration.

My kayak has a narrow front and wider back end. Could not get the loop snug enough on the back to tighten the cable and secure the kayak.
