UNCX Lockers v3 make it possible to lock in liquidity across all price levels. In Uniswap v3, if the current price goes outside of the liquidity range, you can't trade at those prices anymore. By expanding the upper and lower ranges, UNCX Lockers v3 creates a base of tradable reserves. This means users can trade at any price they want, without having to worry about range mismanagement. It also ensures that the person who locks the liquidity always earns the correct fees.
