Client swore an upside-down deadbolt was ‘harder to pick,’ so I set the 2–1/8-inch bore true, backset at 2–3/8 in., latch face flush, and rotated the cylinder 180 degrees — flawless install, spectacularly silly orientation. I kept hardware integrity to the letter (35 in-lb on the thru-bolts, strike set for a 1/8-inch reveal), but the real security upgrade was my ability not to laugh; got any precision-perfect installs that looked ridiculous by request?
And i once had a client convinced their upside-down lock was more secure too! It’s amazing how perception plays into it. Just a heads up, I’d recommend double-checking the alignment of the strike plate; even a slight angle messes with how the deadbolt engages.
Have you considered enzyme concentration impacts? It can really shift results. @aaron_west90, what’s your take on this?
