Cheap and easy

JGKarting 04.01.2025

An easy fix for a strap lock but would not use for any intense use, very good for light bedroom playing etc.

Cool stuff!! Let's see how long they and the strap will last.

Cool stuff!! Let's see how long they and the strap will last.

I have 3 pairs of metal straplocks. On a heavy guitar they wear out, but there's no way without them.

And if the guitar is about 3 kg or less, I like it without straplocks.
This saves weight and less metal ringing. Although straplocks can be lubricated with graphite.

These rubber bands are better than straplocks. The main thing is a hard end of the strap, a wide mount like on Ibanez (Preimium or Prestige) and these rubber bands on top.

Unbeatable Value and Smooth Performance

Nicolas Hroch 26.12.2025

I’m honestly super impressed with the D’Addario PW-FLSB-04BK Flex Lock. For something this cheap, it works way better than I expected. It fits snug on the strap buttons and once it’s on, it stays on — no slipping, no worries. I can move around, play hard, and even jump a bit without feeling like my guitar is about to fall.

The material feels durable and flexible at the same time, and it’s incredibly easy to install. No tools, no hassle — just pop it on and you’re good to go. It also doesn’t mess with the look of the guitar, which is a nice bonus.

For the price, this is an absolute steal. If you want a simple, reliable strap lock that does its job perfectly without spending a lot of money, this is 100% worth it. I’d definitely buy it again and recommend it to anyone who plays guitar.

Flex it is.

Stantoine 18.12.2024

Being made of rubber, this lock can be quite easily fitted over the guitar strap pins without having to unscrew them, unlike some other brands.
