Zanda Jura cylinder deadbolt buying guide
Jura covers a single and a double cylinder deadbolt, both in brushed nickel, a small, focused two-product range.
Single vs double cylinder
A single cylinder deadbolt locks with a key from outside and a turn knob from inside, the standard choice for most external doors, while a double cylinder needs a key on both sides, generally used where a nearby glass panel could otherwise be reached through.
Comparing to other brands
