You are aware that different vendors of lock-sets will have different splines for their individual lock-sets, which means you will be changing the entire lock-set, no just "knob to lever."

Because mfg. will tend to, as a marketing strategy, sell to established vendors, like ACE, TRUE VALUE and MENARD'S, for example, who have a broader market acceptance of "sale" items, rather than to, "quick turn-over," vendors like amazon.

I've always found that establishing a "recognizable" rapport with local hdw. vendors leads to timely notification of planned obsolescence of inventory.

You might consider broadening your horizons.

HI Snoonyb

Thanks for your reply. Help me understand the first sentence - You are aware that different vendors of lock-sets will have different splines for their individual lock-sets, which means you will be changing the entire lock-set, no just "knob to lever."

I am reading this to mean that we are replacing all of the hardware that goes in the hole in the door. Is that what you mean? We are so new to this, and don't know what we don't know, so I want to make sure I make use of everyone's knowledge and experience. Tell me if I am misunderstanding what you mean by the first sentence.

Your idea about reaching out to a local hardware vendor is a good idea. We had a similar experience with a local plumbing supply store that we had done business with a couple of times. They know we are budget conscious and when they were planning to get a new faucet model, they sold us the discontinued floor model at a substantial savings. We both won, they were happy to be rid of the floor model and we were uber happy about the great faucet we were able to get (that otherwise would never have been in our price range) at a price we could afford!

It didn't occur to me to try this with a hardware company! I imagine that there must be local hardware vendors here in Vancouver... I will have a visit with Google and see what I can find.

Thanks for the tip - this is an avenue that hadn't occurred to me!

"I am reading this to mean that we are replacing all of the hardware that goes in the hole in the door."

Thats correct and unless you stay with the same mfg. you have, you'll find that "knob to lever" will probably not work.

When you visit the individual lock mfg. web sites, you'll find a PDF of specifications as well as installation instructions.

Remove one of the passage lock-sets in it's entirety. Make a note of the dia. of the door drillings and where the center of the knob hole is back from the edge of the door.

There is a learning curve in locking devices, but it is short with a lot of similarities between products.
