Are Strap Locks Worth It? Do They Actually Keep Your Guitar From Dropping?

Short version, because I know that's what you came for: yes, for most gigging or standing players, strap locks are worth it. They're cheap insurance against a very expensive accident. But they are not magic, they don't fix the problem that actually drops most guitars, and a two-dollar rubber washer solves the same thing for a lot of players. Here's the honest picture from someone who has watched guitars hit the floor and then had to glue the headstock back on.

What a strap lock actually does

A standard strap button is a little mushroom of metal with a screw through it. Your strap has a slot punched in the leather, you stretch that slot over the flange of the button, and friction holds it there. That's the whole system. It works fine until the leather stretches out, the flange is a little small, or you swing the guitar around and the slot rides up over the edge. Then the strap comes off the button and the guitar goes wherever gravity wants it.

A strap lock replaces that passive friction fit with a mechanical latch. You swap the factory button for a post, and a spring-loaded collar on the strap side clicks over that post and physically holds on. To get it off you have to pull a pin or a sleeve. It cannot walk itself off the button the way a plain strap can.

So the value proposition is simple and real: the most common way a strap detaches, riding up and off the button, is exactly the failure a strap lock is designed to prevent. That's not marketing. On that one specific point they do what they say.

The failure nobody talks about (it's the screw, not the lock)

Here's the part the packaging won't tell you, and it's the reason I roll my eyes a little when someone treats strap locks as a guarantee. Most guitars that end up on my bench with strap-related damage didn't fail at the strap. They failed at the wood. The screw that holds the button, lock or not, pulled straight out of the body.

Think about how a strap button is anchored. It's one wood screw biting into a hole in the body. Every time you sling the guitar on, lean it against an amp, or let it swing on the strap, that screw wiggles a hair. Over years, the hole slowly wallows out and the threads stop gripping. One day it lets go. If you've bolted a fifty-dollar strap lock to a button whose screw hole is already chewed out, congratulations, you now have a fifty-dollar strap lock lying on the floor next to your guitar.

The fix is cheap and boring. If a strap button ever feels loose or spins freely, don't crank the screw down harder and hope. Back it out, pack the hole with a few glue-coated toothpicks or a properly fitted hardwood dowel, let it dry, and re-drill a clean pilot. Now the screw has fresh wood to bite. Do that before you spend money on locks, because a strap lock in a stripped hole is worse than useless: it gives you confidence you haven't earned.

Schaller, Dunlop, and the rest: does the brand matter?

The two you'll see most are Schaller and Dunlop, and both are good. They just get there differently.

Dunlop's Straplok Dual Design uses a groove-and-ball collar that snaps onto the post with an audible click and spins freely so the strap doesn't wind up. Dunlop says the design is release-tested to 800 pounds, which is far more than any guitar will ever ask of it. The nice thing about the Dunlop system is that it's self-contained; once it clicks, it clicks.

Schaller is the original, and worth one warning if you're buying used or looking at an older set. The classic Schaller lock is held together by a small nut, and that nut can loosen over time if you don't put a dab of thread locker on it. Plenty of Schaller "failures" over the years were really just a nut that backed off. Schaller redesigned the system as the S-Locks, which added a set screw and a knurled thumb wheel so it stays put without Loctite, and permanently attached the button screw. If you're buying new Schallers, get the S-Locks. If you inherit an old set, check that nut.

Beyond those two, Loxx, Grover, D'Addario, and Hipshot all make locks that work. Honestly, for a guitar, any of the reputable brands will outlast the instrument. Don't agonize over it. Pick one, install it correctly, and move on.

The free hack: Grolsch washers

Before you spend anything, know that there's a genuinely good budget option that has kept working guitars on working shoulders for decades: the rubber gasket off a swing-top Grolsch beer bottle. It's a thick rubber ring that stretches over a standard strap button on the outside of the strap and stops the leather from riding up and off. Jeff Tweedy and Nels Cline in Wilco reportedly use them exclusively, which tells you they hold up fine on a touring stage.

They shine on Fender-style buttons with a wide flange, where there's a good lip for the washer to sit behind. On guitars with smaller or more tapered buttons, the washer can pop off more easily, and that's where a real mechanical lock earns its money. You can buy the rubber gaskets by the bag from homebrew suppliers if you don't feel like drinking your way to a set. At roughly pocket change apiece, they're the highest value-to-cost item in this entire article.

So do you actually need them?

This is where players argue, and I'll give you my honest take rather than mush. If you play sitting down at home, you almost certainly don't need strap locks. Guitars don't leap off laps. If you stand up, move around, play out, hand your guitar to a tech, or own an instrument you'd be genuinely sick to damage, then yes, put locks on it, or at minimum a pair of Grolsch washers. The downside is a few dollars and ten minutes; the downside of skipping it is a cracked headstock or a caved-in top, and I've repaired plenty of both.

The one thing I'll push back on hard: don't let locks make you complacent about the wood. A lock secures the strap to the button. It does nothing for the button's grip on the body. Check that your strap buttons are snug a couple of times a year, fix any that spin, and you've addressed the failure that actually drops guitars. Do that, add locks or washers for the swing-off scenario, and you've covered both ends of the problem for less than the cost of a set of strings and a coffee.

If you're shopping for your next instrument, it's worth a look at what's on the wall in our guitars in stock collection; every one gets a proper once-over on the bench, strap buttons included, before it goes up.

FAQ

Will strap locks damage my guitar?

No, if installed right. Most locks reuse the existing screw hole. The only thing to watch is that the new post's screw fits the hole snugly; if the original hole is already loose, fill and re-drill it first so the new hardware bites into fresh wood.

Do I need to drill new holes to install strap locks?

Usually not. On most electric guitars the strap-lock button uses the same screw and the same hole as the factory button. Occasionally the supplied screw is a slightly different diameter and the hole needs a filler-and-re-drill, but you're not carving up the body.

Are the cheap Grolsch washers really as safe as real strap locks?

For a lot of guitars, close enough. On wide Fender-style buttons they're very secure. On smaller buttons, or if you're doing windmills, a mechanical lock is more positive. Either one beats a bare button, which is the actual risk.

My strap button spins freely. Is that the strap lock failing?

No, that's the wood, and it's the more dangerous failure. The screw hole has stripped out. No strap lock fixes that; you have to re-anchor the screw in solid wood with a dowel or glued toothpicks and a fresh pilot hole.
