Dunlop Straplok Black Dual Design

I just finished installing these.

Pros: good looking (subtle), easy to mount, clear instructions. You will need two tools. A Phillips screwdriver, evidently, but also something like a needle point nosed pliers to get the retainer clip to snap into the locking pin?s shank groove. Unless you have steel fingers.

Cons: I?ll let the instructions speak for themselves (the caps are Dunlop?s ):
"Maintenance: It is important to periodically maintain the Straplock system. Keeping the ball bearings and the locking pin lubricated is VERY important, as is making sure there is nothing inside the strap button. We recommend the following items to assist you:
1. Cotton Swabs
2. Lubricant Spray"

Frankly, how is one supposed to know what "periodically" means in this context? Is the alternative to this vigilance/effort on the part of the buyer that one day the locking pin, and therefore the strap, might get stuck on the guitar? This is a bit of a concern since one of the locks is tricky to release. So I guess it already needs lubricating...

Jeez Louise. Wish I had known, cause these don?t come cheap. I got my six-year old the Harley Benton Security Locks BK at a fraction of the price. They work fine and don?t require maintenance.

In use with ESP ltd 600 Gary Holt guitar and a Minotaur Strap. Easy to install on the guitar ( tip: follow the steps on the small manual ). Once installed it sticks out a bit . So had to adjust the custom case that went with the ESP ( cut out some isomo and replace the fur in the case to make the guitar fit again ).
Also use the screws that come with the locks ( don't re-use the guitar screws ) as the heads of the screws are adapted to fit the locks.
Very solid product and well worth buying with any guitar to avoid it from falling when strap comes loose.
