I quickly discovered it doesn’t fit my door. A steel clad door btw that came pre-hung and already factory predrilled for the lockset. My old corroded residential Yale lock has been on it for fifteen years.
The Hole for the cylinder isn’t far enough over. The cylinder flange won’t line up with the flange on the latch. It’s at least 3/8" off. You’d ruin the door trying to drill a new hole further over.
Is this problem common for Commercial Locksets? Are you expected to buy a door and drill it yourself for commercial locks?
I’m very puzzled because these days a lot of steel clad, exterior doors come predrilled for the lock set. It’s an industry standard fit. I was just flabbergasted that this commercial lockset wouldn’t fit. I even held up the install template on my door to confirm the hole isn’t in the right place.
There are two standard backsets (distance from edge of door to the center of the main hole) for the vast majority of all locksets, which are 2-3/8" and 2-3/4". Sounds like you bought the wrong one.
If for some reason you want to open up the hole (rather than just get a latch with the correct backset), just get a reinforcement plate, it looks like this. Runs about $20, comes in a variety of colors. You slip it right onto the door and screw it in, then install your lockset. Just make sure you get one with the right backset (2-3/4")!
Looks like I’ll be getting a lock from Lowes. I quickly looked through Grainger’s commercial locksets and everyone I checked said, in the catalog description backset - 2-3/4 In. I only checked stainless steel ones under $90.
I’ll look at the packaging closely at Lowes to confirm the lockset is 2 3/8 backset.
I was looking at the locksets at Lowes online and it looks like most of them are designed to accommodate either backset, which may explain why you haven’t had this problem in the past.
Residential locks are usually 2 3/8 while commercial locks are usually 2 3/4, but they can vary. Many of the locks you buy at Lowes or Home Depot are adjustable so they can fit either standard, but there are quite a few locks that are specific to one size or the other.
There are also some oddballs out there. The front door of my house happens to have a 5 inch backset. I had to buy a regular doorknob and then also special order a longer bolt to go with it.
:nitpick:
In what way are they not interchangable? :dubious:
A 2-3/4" backset commercial lockset most certainly CAN be used as a residential lockset.
For that matter, I’ve yet to come across an exterior residential door that was predrilled for a lockset, that was not a 2-3/4" backset. (And I’ve installed hundreds of them, at the least.) Interior residential doors and latchsets* are predominantly 2-3/8" backset.
*They can be lockable, but the lock mechanism is generally a push button or turnable button style that is unlocked with a small wire or screwdriver, that is provided with the latchset. Latchsets do not have a key.
Commercial duty latchsets (no locking mechanism) are 2-3/4" backset.
I’ve been switching out locks on my house and for friends for most of my adult life. Never ran into this before.
