Kaba Simplex 7104-03-41 Thumbturn Mechanical Pushbutton Spring Latch - Secure Door Lock for Commercial & Residential Use in Offices, Schools & Homes

LOVE this lock. Although a lot of the KABA product lacks description. I called KABA direct 1-800-849-8324 and they helped me with deadbolt vs deadlatch,.. Backset... and what finish I was interested in. Got the right model numbers and ordered correctly. Lock will install in a standard deadbolt hole You will need to drill 3 additional holes though. 1 @ 3/4" and 2 @ 1/4" but they supply a paper template, Holes need to be drilled level and straight ! The Lock fits into the cavity of where I had my old deadbolt and covers the hole side to side. Love the fact that I have no batteries to replace. Solid lock ! Bump Proof ! Now I don't have any keys to carry ! You program your own code into the lock.
