All my guitars have the DiMarzio cliplock system installed, Not once have these failed me!
Just purchased the guitar end sections this time as the straps are interchangeable.
They came with two different types of screws(short and narrow for Gibson or Fender etc... and Long and thick for Ibanez/Schecter etc..) to replace the strap pin screws on your guitar.
Installation is very easy, Just unscrew your original strap pins/screws and assemble the cliplock system as shown in the instructions using the supplied nylon washers and bushings and simply screw the assembly into the existing strap pin screw hole. Simple idea but it has saved me many euros over the years by preventing the inevitable 'strap popping off' problem especially on Gibson guitars! With their ridiculously small strap pins!
This really is an install and forget about it product... Essential.
