FenderFender 990819000 Strap Blocks (2 Pair), 2.5 cm*4.0 cm*0.25 cm

These things are great, doesn't take a lot of effort to put on in my opinion but they are quite strong. My guitar strap is now much more secure than it was and should last longer too. The best part about them is, no modifying of your guitar or strap is required! Totally recommended, especially if you have an expensive strap and want it to last longer, or, want to improve the security of your strap without any real effort. Every guitar with standard strap buttons should have these.I'd have prefered two pairs of black rather than black and red though, not sure why Fender decided to do that. Fitted fine over standard electric guitar buttons and also a through-jack style button on my daughters electro-acoustic. Also fitted onto oversized Jackson strap buttons, which takes a bit more effort to get on and off, but I suppose that just makes them more secure.

Bought these strap locks for my Fender Jazz Bass. They look great and work a treat.The strap section is held on with a large washer and a nut. I bought an extra strap so I could leave these on permanently.Very happy with these strap locks.

Nice product. Very positive locking and don’t need fingers like a vice to squeeze the lock/unlock button. Fitted 3 sets in 15 minutes, ordering 4 more for the rest of the guitars now I’ve seen them and assessed the quality.Update:after a few days one has started popping out and dumped my expensive guitar on the floor several times. They are going back.

These strap blocks from Fender are a great cheap option to add security to your guitar strap.You get 2 sets of blocks i the pack, one red and one black. I put one set on my Squire Stratocaster over an Earnie Ball guitar strap. They are a little tough to initially get on and the guitar strap button has just enough height to accommodate both the strap and the block but this all adds to the security and the feeling of security. Once they are in, it is quite difficult to spin the end of your strap around on the button. I guess this can be seen as both a positive and a negative. The blocks themselves feel like they are made of a very high quality and durable materialI would still say normal strap locks will be stronger if you want to spend the extra money, but these blocks do a great job and mean you can switch guitar straps easier if you wish to do so, unlike strap locks.

These are literally just little rubber O rings with Fender embossed. Simple but they work. Haven’t yet had a guitar drop while using these.Easy to slip on and off (well with a bit of strength). But less faff than strap locks you have to screw in and then fix with wooden dowels when they drop out.So these Fender locks are handy to have in your gigbag. And they’re discrete too.

IN A NUTSHELL: Yes, get them. They're a simple, unobtrusive and very cost-effective way of stopping your strap parting company. In fact, unless you're regularly thrashing around on stage with a guitar that cost a four-figure sum, you probably won't ever need any other strap locking device.IN DETAIL: Strap Locks are an important item for a guitarist/bassist to consider (essential in the case of those that actively gig), yet the choice is far from clear. Several options exist for mechanisms that replace the instrument's standard strap button, but consensus on which is the most effective and worth investing in does not. For some time now, some players have spoken of the little rubber washers found on large Grolsch bottles as a cheap-but-effective alternative. Apparently Fender knew of it, too, since they've now made their own versions specifically for 'blocking' instrument straps. I've seen some people say that these Fender ones are a rip-off, since you can get a similar thing 'free' from a couple of large Grolsch bottles. I like beer as much as the next guy, but if you can get two big bottles for £2.99, then you live next to the world's best off-license. For most people, these Fender ones will set you back less when all is said and done. Moreover, you get four to a pack so we're actually talking four bottles-worth here.Big question then; do they work? Yes, absolutely. It takes a bit of effort to fit them on, which is good - it indicates the kind of force necessary for them to come off again. Note that they're called strap BLOCKS rather than LOCKS - this isn't a device that can outright lock your strap against the instrument. Rather, what it does is add a lot of resistance to any movement of the strap off the button. If, like me, you're still at the stage of jamming on your room with a budget instrument then I can confidently tell you that these strap blocks, for an outlay of three pounds, will be all you need; they'll prevent the strap popping off at one end. If you were a regularly gigging musician with a more expensive axe to protect...? That's partly a personal judgement as to what you feel secure with. But these would certainly serve as a stop-gap until you settled on a locking device, at the very least. Being very unobtrusive (well, the black ones at least)they'd also be a good choice for those who don't want the aesthetic clutter of a strap lock extending off their instrument.All-in-all, I think Fender have made a valuable addition to the guitar-care market with these and, for the price, they're worth adding to everyone's gig bag.

does the job

Whilst there's cheaper versions of these I went with fender as a hope of quality. You get 2 pairs one red one black, would be nice if you could choose red or black.As for function they work really well. They go on snug but with out being to hard to put on or remove. They hold the strap nice and solid. Whilst you're not going to do guitar spins with these that's not what they are for, get some proper locks for that.Ultimately they stop the strap slipping off, which has happened to me in the past. On older guitars I used mechanical system like the Schaller or Dunlop systems but for what I do these are much less effort to fit and more than strong enough.
