    Great Lock Box for Customizatio

    Posted by Tommy on Nov 6th 2023

    The Emtek 3300 Mortise Lock Box is perfect for those who like customizing their hardware. You can match it with your preferred knob or lever, which is awesome. However, be ready to purchase the cylinder separately, and the cost can add up. The flexibility it offers is fantastic, but it's essential to budget for the extras.

    A Sturdy Lock, but Not without Quirks

    Posted by Walter on Oct 26th 2023

    The Emtek 3300 Mortise Lock Box from ZenSupply is solidly built, and I love the flexibility to use a thumbturn, lever, or knob. The drawback is that it doesn't come with the cylinder. So, that's an extra purchase and hassle. But if you're handy with locks, it's a good choice for security and style.
