Padlock

I have a small padlock on my washboard.

It needs a 5mm shackle bar or smaller.

Ideally I'd want three keyed alike padlocks (so I can lock the lockers) that will be able to be marine environment corrosion free. Is this a unicorn?

Those I've used so far are rubbish, and have rusted and failed amazingly quickly

Any recomendations?

(why do we call them lockers when they don't?)


FWIW, I had three cheap Masterlock combination locks and - with twice yearly greasing - all three lasted 9 years. By the end the shackles on all three looked pretty awful with rust but they still functioned and were showing no sign of ceasing to function. The non-ferrous (brass?) bodies were in perfect nick.
 
After years on a swinging mooring, I never use key padlocks. Combination locks can be any number you want. They are only to stop the casual thief, not serious criminals who have grinders!


That's exactly my strategy. I want to put off casual thieves whilst making it easy for equipped thieves to get in without taking and angle grinder to GRP or the OB bracket.

I've no idea if, on average, that's the right strategy. (Not least because I fear that an angle grinder is less effort than breaking even the weakest padlock.)
 
After having padlocks that rusted after one season I got 3 stainless combination locks marked "Shield" that have lasted for years.
They allow you to sert your own number. Only one gave me trouble as I could not open it so ihad to scrap it.
 
I bought a combination padlock for the wee boat about 4 years ago, from a recommendation on here, something like marinepadlocks?? And it has been faultless. Just works, everything is smooth and no sign of rust despite boat being in the water all the year round.I have never oiled or lubed it. Sorry its not much use without the supplier, but they have been mentioned on the forum more than once so someone else may remember.
 
I never found graphite any good on padlocks. Preferred GT85 lube spray that seemed to last the season.
I've had success with graphite, but only after thoroughly cleaning all oil out first - I agree that GT85 is great, especially when comparing the cost to supposedly "boat specific" alternatives.
