Question:

Alcoa no longer makes these. And I have only four pieces of the -AA version of The latch. We need to find a solution for this client. He is willing to take alternate recommendations. They need both latch and the strike for production. Each production item requires 21 latches. They are planning to to make ~20 items.
So please let me know what you can come up with.

Answer:

The tension load this camloc 37L33 or 37L52 latch can Carry is

4500 pounds ultimate = 20000 Newton

3000 pounds working around 14000 Newton

Furthermore 37L33 is a secondary lock version steel cadmium plated, rivet mounting method, long length

This means we can help you with a secondary lock version of the PAH series.

if your customer is accepting 18200 Newton as maximum load, then please consider the PAH-2603-TRIG ; otherways you'll have to transition to PAH-385-TRIG which can take 35000 Newton. only disadvantage is if you take the PAH series, your weight goes up. a 37L33 weighs around 0,25 kg whereass on PAH weighs 2,5kg ; so 10 times more!

PAH-2603-TRIG 18000 Newton

PAH-2603-TRIG latch

PAH-385-TRIG 35000 Newton

PAH-385-TRIG strongest latch on the planet with secondary lock

we can help you transition following part numbers

37L52-1-1AA, 37L52-1-2AA, 37L52-1-2BB, 37L52-2-2BB

37L33-1-1AA

37L33-1-4AB

37L33-4-1AB

37L22-1-1AC

37L11-1B

37L25-1-1AA

37L15-1A

37L15-1E

37L14-1

the strongest standard latches that exist are the "king" latches (more look-alike as 37L series)
series K24 have an ultimate strength of 13000 Newton, however look to how they deform when the load is on.

advantage, they are adjustable and have the option to add a secondary lock feature. (diameter 8) another advantage is that the weight is even a little bit less then the 37L series (around 0,2kg)

another option are the K935 series, here you see another deformation
(on this test, the latch did not deform, however the rivetting was deformed)
so you can say you can hit around 14000 Newton (the weight of this latch is around 0,4kg)
