Gibraltar Hinged Memory Wing Lock

If you're adding on to your Gibraltar rack, these memory locks are a good way to stabilize any additions without the need to remove everything to slide standard memory locks into place. Still, the memory lock with the key adjustment is a better option, as the wing lock tends to get tangled up in clamps since it's a bit wider than the lock itself (using an L-shaped key with the other locks is a lot less awkward). Regardless, these are plenty serviceable for any rack setup that isn't getting too crowded.
