What are strap locks?

In the most basic sense, a “strap lock” is a tool that helps you to secure and fasten your strap onto your guitar or bass. This device helps to make sure that your instrument does not come loose from the strap and fall off. 

How do strap locks work?

Strap locks work by restricting the moment of the guitar strap over the strap buttons on your guitar. All guitars come with two strap buttons. These are usually located on the body toward the bridge and above the cutaway. 

Typically, you will purchase a guitar strap with a hole at both ends. Most guitar straps even have multiple holes that allow you to determine the length of the strap (how low or high you would like the guitar to sit). 

When you need to stand and perform, the strap holes are slid over the strap buttons which allows the guitar to hang by the strap.

Here’s some of my guitar’s – they all have metal Schaller strap lock systems installed. Same on my other guitar’s too!

In most cases, this works perfectly fine. However, if your strap holes are loose, worn down, or you are constantly running around on stage – there is a probability that your guitar can come loose and fall!

Strap locks work by replacing the strap buttons with specifically designed and machined screws (buttons). These screws have an additional mechanism that is attached to your guitar strap. The mechanism and the button can then “lock” – securing your strap in place. 

The sole purpose of strap locks is to give you the utmost confidence that your strap is securely connected to your guitar, and no matter what you do, they will not come loose. 

Metal, rubber, and plastic strap locks explained

The most common type of strap locks are made of metal. These are an entire mechanism that replaces the stock strap buttons on your guitar and fastens them to your strap. These are by far the more superior version of strap locks that most players tend to use.

Personally, I have metal strap locks installed on all the guitars that I regularly use. It gives me confidence that they aren’t going to fall off midway through playing.

I use Schaller strap locks for my guitars, and highly recommend them for any guitarist. I’ve bought cheaper ones before (“Fender F” style strap locks) and they fell off midway through me playing – luckily I caught my guitar! I quickly replaced them with Schallers. Check out Schaller strap locks on Amazon here.

Rubber strap locks function differently from metal strap locks. You can think of rubber strap locks like a tight rubber washer that sits between your strap and strap buttons. They’re a lot cheaper than metal strap locks, but aren’t as sturdy in the long run. You can check them out on Amazon here.

Finally, you can also get plastic strap locks ones. These function in a similar way as the rubber ones do. That is, you slide them over your strap and buttons – but these have a mechanism that locks them into place, making them a bit sturdier. Plastic strap locks tend to be better than rubber ones – but neither are as good as metal ones. Check out the plastic strap lock on Amazon here.

My opinion: Ultimately, I recommend getting metal strap locks. I use the Schaller strap locks for all my guitars and have never had a problem!

A few dollars can really save you hundreds in guitar repair bills!

How to install strap locks on a guitar:

Removing guitar strap button

Remove the strap buttons

First, remove the guitars strap buttons from the body of your guitar. This is achieved easily by unscrewing them using a Phillips head screwdriver.

Turn the screw anti-clockwise to loosen the strap buttons from the body.

Assemble the strap lock buttons and the washer

To assemble the strap lock button, hold the washer next to the button and push the screw through the button. The screw should pass through easily, but in some cases you may to use a screwdriver and screw it in.

Ensure that the screwhead sits completely flush with the inside the metal button and that the washer is pressed firmly against the flat bottom of the button. 

Screw the strap lock button into the body of your guitar

Once you have assembled both strap lock buttons, you’ll need to screw them into your guitar. Using the Philips head screwdriver, fasten the new strap lock buttons into both sections of the body of your guitar.

In some cases, the strap lock screw may be too short. In these circumstances, you should replace the new strap lock screw with your old ones if you can.

Make sure you screw the strap lock button nice and snug so that the washer is firmly pressed against the guitar and that they do not move whatsoever.

Important: Don’t over tighten the screw, as this can damage your guitar. Once the strap lock has been fully screwed into the body; a final quarter turn of the screwdriver will be plenty to keep it in place.

Attach the strap lock mechanism to your guitar strap

Next, push the strap lock mechanism through the holes on your guitar strap. Make sure that your strap sits flush against it.

Note: Some strap locks come with the washer and nut already assembled. If so, you’ll need to remove the nut and washer before doing this step.

Make sure the guitar strap is the correct way round

Before assembling the locking mechanism to your strap, make sure it’s aligned in the proper direction. This means making sure it is the correct way round.

The open face of the mechanism should be on the bottom of the strap, with the open end facing the tip of your strap.

Assembling strap lock

Attach the locking mechanism to your strap

Take the washer and slide it over the mechanism so that it’s flush with the top side of your strap. Then, take the nut and fasten it to the mechanism, so that it sits flush with the metal washer.

Using a wrench of the appropriate size, tighten the nut. A good way to do this is to get is a tight as you can with your fingers, and then make a full turn with the wrench (or as much of a turn as you can). Make sure to hold the bottom part of the strap lock in place, so that it doesn’t spin around!

Some newer strap locks, like the Schaller S-Lock, have a slightly different way to attach the mechanism to the guitar strap. Check out the instructions for this type here.

Lock your strap to your guitar

The only thing left to do is to lock your strap to your newly installed strap locks. The mechanism attached to your strap will have a pole of sorts. You will need to pull it so that the locking mechanism can slide over the strap buttons. 

Once you pull the pole and slide it over the button, let it go, and you should hear a “click”. If you don’t hear a click, wobble the mechanism back-and-forth – it’s likely just got stuck on the edge of the button!

Do this for both ends of your strap and there it is – you’ve now installed and locked your strap to your guitar and are ready for some risk free rocking! 

This process is simple enough, but if you need a visual aid, check out this video by Fender that goes through the entire process in under 5 minutes. 

Recommended gear: I use the CruzTools Stagehand Compact Tech Kit for small maintenance jobs like these. It contains the screwdriver and Allen wrench heads needed for this job. It also contains a lot of other tools needed to properly maintain your guitar. You can pick one up using this link to Amazon.

Pros and cons of strap locks

The pros of metal strap locks are that they are heavy-duty and are built to withstand a lot of wear. The cons are that they do cost more than plastic and rubber strap locks. Also, you’ll have to install them yourself. However, this tutorial should have made it clear and simple enough for you to understand that installing them is a walk in the park!

The pros of plastic and rubber strap locks are that they are very affordable. Moreover, you do not have to worry about installing anything – you simply slide them over your strap and buttons, and you’re all set. 

The cons of plastic and rubber strap locks are that they are not as sturdy as steel ones. This means that there is a chance they can either break or come loose.

My opinion: I think strap locks are a must-have for any serious guitar player. They’re like a small insurance against the risk of dropping your precious axe.

As someone who used to have issues with my guitar strap falling off – I can confidently say that I’ve never had a problem since installing strap locks! (With the exception of “Fender F” strap locks – they fell off after a few uses, I don’t recommend buying those!)


Strap locks are a must-have if you practice and perform guitar standing up. These little devices will take away the uncertainty of your strap falling off, giving you the peace of mind to focus on your playing. 

Depending on your needs and budget, there are various ones you can purchase. For the most part, they all do a pretty good job!

Installing metal strap locks is relatively simple and shouldn’t take more than 5 or 10 minutes. Just make sure to pre-assemble the parts and make sure they’re fastened tightly to your guitar.
