Single-cylinder deadbolt with adjustable backset

This commercial-grade deadbolt uses a single cylinder operated by a key outside and a turn knob inside. The dull chrome finish resists wear in high-traffic doorways. An adjustable backset fits both 2-3/8 inch and 2-3/4 inch door preparations. Three SC1 keys are included in the box.

Fits standard residential and light-commercial doors

Builders and property managers who need a durable, keyed-different lock for common door thicknesses will find this model suitable. It does not suit doors requiring a double-cylinder deadbolt for keyed entry on both sides. Buyers needing electronic access, smart-home integration or a different keyway should consider other options.

SC1 keyway with three keys supplied

The lock uses the SC1 keyway, a widely copied profile that works with many existing key systems. Three cut keys are provided so spares are available immediately. If your facility uses a different keyway or a master-keyed system, this cylinder will not match.

Questions about this item

Does this D30526 deadbolt need a pre-drilled door with a 2-3/8 to 2-3/4 inch backset?

Yes, the adjustable backset fits doors prepared for either 2-3/8 or 2-3/4 inch backset measurements.

Can I keep my existing SC1-keyed locks and have this cylinder match them?

The SC1 keyway allows a locksmith to re-key this cylinder to your existing SC1 keys.

How do I confirm the D30526 is operating correctly after installation?

The key should turn smoothly from outside and the thumb-turn should retract the bolt fully from inside without binding.
