Kwikset 81691 Reviews

Rated 5 out of 5 by from Performed the required adaptation. I used this to install an older but similar lock. The dimensions were very accurate and the modification easy.

  • Is this the correct extension kit for a standard residential deadbolt? I think deadbolt is Kwikset 660 series.

    A. The Kwikset 81691 is for the 780 deadbolt. You will need the Kwikset 86129 for the 660 deadbolt.
