Mortise Lock Springs: A Breakdown of Good, Better, and Best

Interior mortise locks are the workhorses of our homes, quietly doing their job day in and day out. While often overlooked, the spring within the lock plays a crucial role in its smooth operation and longevity. Let's break down the different types of springs you might find in your mortise lock.

The Builder's Grade: Stiff and Brittle

You've probably encountered this type if you've ever dealt with a newly constructed home. Builder's grade locks typically employ stiff springs. While these springs might seem sturdy, they can lead to a rough, jerky feel when operating the lock. Moreover, they're notorious for breaking, often leaving you with a lock that's stuck in one position. It's a classic case of "cheap and cheerful" until it isn't.

The Residential Standard: Softer but Still Susceptible

Most homeowners are familiar with this middle-of-the-road option. Softer springs offer a smoother operation than their stiffer counterparts. However, they're still vulnerable to breakage, a common culprit in lock repair calls. It's a bit like Goldilocks and the Three Bears – not too stiff, not too soft, but still not quite right.

The Premium Choice: Smooth and Durable

If you're looking for the ultimate in lock performance, look no further than a mortise lock with an easy spring. These locks operate with buttery smoothness and are far less likely to break. While they typically come with a higher price tag, the investment in long-lasting, trouble-free operation is often worth it.

So, the next time you're considering a new interior door or replacing a troublesome lock, pay attention to the spring. It might just be the unsung hero of your home's security.
