  • Grade 1 rating meets the highest security standard for residential deadlocks

Grade 1 Single Cylinder Deadlock

This Grade 1 deadlock provides high-security protection for residential and commercial entry doors. The single cylinder design allows keyed entry from the outside and thumb-turn operation from the inside. A solid bronze alloy case and bolt deliver maximum resistance against forced entry attempts. The lock is supplied new in a polished chrome finish.

Verify Door Prep and Strike Compatibility

Confirm your door is prepared for a jimmy-proof surface-mounted lock rather than a mortise or standard tubular bore. The included angle strike is designed for frames with a recessed rabbet; a flat strike will not align correctly. Check that the existing cylinder cutout matches the recessed collar dimensions. Ensure the 5-pin SE1 keyway suits your existing key system or plan for rekeying.

Solid Bronze Construction With Hardened Hardware

The lock body and bolt are cast from high-strength bronze alloy for durability and drill resistance. Hardened drill-point screws anchor the unit firmly to the door and frame. A recessed cylinder collar protects the SE1 keyway from wrenching and pulling attacks. Polished chrome plating resists corrosion and daily wear on both interior and exterior surfaces.

Questions about this item

Does the lockset include a flat strike plate or must one be purchased separately?

The lockset ships with an angle strike included; a flat strike is not supplied and would need to be sourced separately if required.

Is the Grade 1 rating the only security tier offered for the 1786-26 model?

The 1786-26 is listed as Grade 1 only; no alternative grade is mentioned for this model.

How does the SE1 keyway affect key duplication in practice?

The 5-pin SE1 keyway accepts standard SE1 blanks, so keys can be cut by most locksmiths or hardware stores that stock that keyway.
