LOCK-IT Guitar Strap Olive Green Cotton Patented Locking Technology (strap lock)

The built in strap lock is the best

I would buy another of these straps. A well made strap. Made in USA. And the spring closure seems to work well. Its on a Godin Redline 2 here.

2nd lock it strap I've owned, it's locking mechanism is a spring loaded piece of what I believe is plastic. I like the design much better than the rubber washers used to "lock" the strap in place

The locking mechanism is pretty stiff and difficult to attach to your guitar with one hand. The stiff end sections don't fold so it's tough to stash in the guitar case. Going back to the Schaller locking system which lock on securely using one hand.

Have a Seagull Entourage Accoustice/Electric. May have one of the biggest endpin/jack's out there and this does fit over!! Barely, but it does. Well made, very comfortable.
