With the Schaller S-Locks presents Schaller the next generation of the famous Security Locks . Introduced in 1981, the guitar strap buckle system now features an extended 6mm screw axis for easy attachment to thick leather straps, while the new Lock-Wheel can be tightened and locked in place with a clamping screw. In addition, the specially turned 4mm thread of the strap pins ensures a secure hold in most common instruments.

Bought 3 sets of Schaller S-locks finished in Nickel. Happy with the delivery time to the UK. Less happy that despite staying at home to receive the package, UPS left it outside the frontbdoor without knocking. Luckily Insaw the "delivered" email notification and rescued my precious Schallers! One star deducted for craftsmanship as one of the six hex-head screws had an over sized pocket causing the allen key (not supplied) to slip. I used a slightly larger Imperial sized alternative and it fitted fine. Three guitars now fitted with these locks which are still the best quality out there in my opinion. I also deduct a star for value due to the small quality issue. I dont want defects from Schaller.
I’ve got these on all my guitars now for peace of mind and they’re great.
My only issue with my order was that it took 2 weeks to get to me and I had no communication about shipping so I had to chase it up. I did get a response but it was a very blanket, your order has been posted and should arrive soon, no real customer service or apology or anything, so although they’re a bit cheaper here I probably won’t order again for £8 shipping if that’s a regular occurrence. (I don’t mind waiting for orders as long as I’m told beforehand, but when I’m ordering and it’s in stock, I don’t think it unreasonable to expect it within 5 days or so)
