About RJ-Sport Heavy Duty Cord Locks, Double Hole

Cord locks are a great solution to keep your strings in place, whether they be drawstrings or laces. The determine factor of a cord lock is its gripping power, that’s why RJ-Sport Cord Locks use premium stainless steel spring. You may notice they are a bit harder to push when you’re threading the cords, but they do grip a lot better. FAQ Q: Can these work with flat laces?A: Yes, they surely can. If your laces are the flat and thin type, make sure to press the button to release the lock before pulling the laces. This is the right way to use these locks, for any type of cords or laces. Q: Can I move the fastener lock without pressing the button?A: That's not the correct way to use this product. If you drag the laces anyway with the cord locking, the friction will damage your laces and those extra thin laces may slide under the clamp disc, and you will have to reinstall the lock. Q: How to put these on shoelaces?A: Press the button down and hold it while threading the laces though the holes on the lock. Once the laces are through, release the button to lock. The cord lock will keep your laces in place. It’s also recommended to make a simple knot in the end of the laces so you won’t accidentally slide them out of the lock. Q: Are the springs strong?A: Yes, they are strong. These RJ-Sport Cord Locks are widely used with sneakers and boots, which customers wear to run marathon or cycling, without any problems. Q: Can these be used for 1/4’’ cords?A: No, they can’t. The cord hole diameter is 3.5mm, 1/4’’ rope can’t go though. But if you use them with 1/8’’ cords, they are perfect. Please do a little measurement to see if your laces or strings are within 3.5mm.
