When it comes to architectural hardware, DIN locks might not be the flashiest part of a project—but they’re one of the most critical. And not all DIN locks are created equal. When manufacturing our Prostyle locks, we’ve obsessed over every small detail to make them better for installers, more secure for users, and more durable over time.
Here’s a closer look at the thoughtful engineering behind our DIN locks, and why they stand out in the market:
🔩 Grip Tight Follower – Secure Fit, No Wobble
A common issue with lower-quality locks is the spindle losing its seat over time, leading to loose levers or handles. Our DIN locks feature a grip tight follower—a subtle but essential detail that keeps the spindle securely in place, even after repeated use. The result? A firmer handle action and longer-lasting reliability.
🔁 Tool-Free Reversible Latch – Switch Hands in Seconds
Handing doors has never been easier. Our easy reversible latch allows you to change the latch direction without any tools. That means quicker installation on site, no fumbling with screwdrivers, and fewer errors. It’s especially valuable for large projects or retrofits where speed and accuracy matter.
📏 Universal Sizing – One Lock to Fit Them All
Every model in our DIN lock range shares the same universal case size and footprint. Whether you’re installing a Sashlock, a Latch, or a Bathroom Lock, you can trust the case dimensions will match. This simplifies door preparation, reduces stock complexity, and ensures seamless upgrades or replacements across different door types.
🔐 Double Throw Deadbolt – Twice the Protection
Security isn’t just a feature—it’s a necessity. Our double throw deadbolt provides an extra layer of protection by extending further into the strike when locked. That means enhanced resistance against forced entry, and greater peace of mind for end users. Ideal for residential and commercial applications alike.
🛑 Anti-Rattle Strike – Quiet, Even Under Pressure
A secure door shouldn’t sound like a loose one. Our anti-rattle strike plates eliminate the common issue of door movement noise, especially in high-traffic or high-use areas. With tight tolerances and integrated buffers, they ensure the door closes snugly—and stays quiet.
🛠️ Built to Last – Backed by a 10-Year Warranty
We don’t just talk about durability—we back it up. Every lock in our DIN range is covered by a 10-year warranty, a testament to the quality of our materials, craftsmanship, and design. It’s peace of mind for you and your clients, knowing the hardware won’t let you down.
