  • Grade 1 certification confirms high-security deadlock performance

Grade 1 Jimmy Proof Deadlock

The Progressive 1776-26 is a Grade 1 single cylinder deadlock built for residential and light commercial doors that demand the highest industry security rating. Its solid high-strength bronze alloy case and bolt resist forced entry while the polished chrome US26 finish withstands daily exposure to weather and handling.

Flat strike and recessed cylinder collar

A flat strike plate simplifies mortising into standard door frames without special routing, and the recessed cylinder collar shields the 5 pin SE1 keyway from wrenching or pulling attacks. Hardened drill point screws anchor the assembly firmly, and the shutter guard blocks manipulation even if the outer cylinder is compromised.

Upgrades from standard Grade 2 or unrated deadbolts

The jump to Grade 1 is justified when building codes require it or when the opening protects high-value contents and sees heavy traffic. Buyers who need double cylinder operation or electronic access control should look elsewhere, as this model provides mechanical single cylinder locking only.

Questions about this item

What lock grade does the 1776-26 meet?

The 1776-26 meets Grade 1, the highest residential and commercial security rating for deadlocks.

What door preparation and strike type does the 1776-26 require?

It is a surface-mounted jimmy-proof deadlock that uses a flat strike, so no deep mortise pocket is needed.

How is the cylinder secured during installation, and what mistake should be avoided?

The hardened drill-point screws fasten the solid bronze case; the common error is not fully tightening them so the recessed cylinder collar seats properly.
