Help finding replacement exterior lock?

[STB]

Hi all,

My boat's main entry door is 1" thick and I'm having trouble finding a replacement key-lockable knob/latch. Options for thin doors seem few.

The most critical dimensions are:
-- The door is 1" thick
-- The center line of the lock is 1-3/4" from the door's edge.
-- The door opens outward and, from the outside, the hinges are on the right and lock on the left.

Other far less critical details:
-- The present faceplates are 1-1/4" wide by 4-1/2" tall (inside and outside are the same.
-- The screw holes are 3-5/8" apart and center-line.
-- The hole for the knob and the hole for the lock are 2-1/4" apart and center-line.
-- The bolt hole from the edge in is 5/8"

Pictures are attached.

Can anyone suggest a replacement that will cover the old holes, give me an exterior key lock, and look appropriate for a trawler?

My backup plan, which I'd really like to avoid for cosmetic reasons is to fill the old large holes (lock and knob) with dowels, putty fill the old screw holes, refinish, and install cosmetic door knobs on both sides, continue using the barrel bolt on the inside, and add a padlock on the outside. (Right now I lock up when I leave via the aft door).

Many thanks!

Perko would likely have a product that fits, but as the thread below discusses, Perko mortise locks have been poor quality for some time.

I had 8 old Perko locks (broken failures) on board from the PO to reinforce that view!

My solution is referenced in post #23 & #28 of the thread below, with pics. The new Olcese Ricci locksets are going great!

Hey Brian,

Thanks much! Any idea who might ship those Italian or Australian locks to the US? The ones that were described as having 11-13mm box sizes thicknesses or that could work with doors as thin as 25mm and had the lock and knob/handle at 45mm look like they'd work. But, the pages didnt list a US distributor. Many thanks!

Fisheries Supply

For doors down to 3/4” thick.

Also look at screen door hardware.

I saved the Fisheries Supply link. I have the Perko junk on my doors too. I had to repair one of them, it was a bad spring so it was easy to fix. Anymore issues and I will probably replace them.

Hey Tiltrider1,

That one didnt have a key, but this one does:

Unfortuantely, the part number they are listing isnt coming up on Merit's site and they dont have the full specs, so I cant verify the centerline. Will call them in AM.

Many thanks!

I bought them via my local hardware store which has a specialist locksmith counter embedded in it. They sourced from a wholesale supplier, link below. This link has a good dimension drawing in it also.

Subsequently I also found the same model at an Australian online supplier:

https://www.theboatwarehouse.com.au...wgwM9vw-yLVmuw5FPNq3xaKa7PwE9NEwaAih8EALw_wcB

I'm not sure whether either of these businesses are able to supply to you. The locks are relatively expensive (prices are Australian dollars) and shipping would add a bit as well. I would think that some online searching, or email to the manufacturer may well turn up a local supplier for you.

Edit: I just noticed the first link was also part of my post in the thread I linked too, so a bit of duplication - sorry!

Thanks everyone!

I called fisheries supplies today. They have one that looks good to me, but none of their support folks knew the product and couldn't help me to verify dimensions or left handed vs right handed. They sent me to Merit's web site, which didn't list the product, at least under the number that Fisheries Supply claimed as the manufacturer's number.
I'll call Merit tomorrow. I missed them today.

If fisheries supply doesn't work out, I'll order the one form the Boat Warehouse in Australia. Just hoping to avoid the complexities of the international buy.

Many, many thanks!

They have quite a range of locks. The above link will take you to the types I was thinking of.

Sorry I just caught up with this question today.
