Coin locks size?

[tkuper05]

Is there a standard size of lock for arcade coin doors? Circa 1985.  I drilled mine to gain access to the insides.

Depends on the game, but likely 7/8".

I have them on my site:

Unless it's using a round key, there's no need to drill:

7/8th as Peale says is the usual size for metal doors, but I've had to do some tweaking by bending the metal plate on the back of the lock to get it tight or loose enough.

7/8" is standard length, but that vintage might have had a 5/8" long. Everything nowadays is standardized at 7/8".

I made the mistake of buying 5/8" locks for my door, because I thought that the measurements were in terms of the width of the lock hole, but then when I installed one the shaft was too short to lock. So I had to go and order the 7/8" locks instead. I think that 7/8" is more or less the "industry standard" for coin doors.

Measure twice, buy once! 

Take a bolt and thread a nut onto it almost all the way.  place the bolt through the hole so the bottom of the head is resting against the outside of the lock hole.  Take something flat and place it against the the spot where the cam would hit.  Now spin the nut until it hits the "cam".  Take out the bolt and measure from the bottom of the head to the bottom of the nut.

Note: you can buy offset cams (typically 1/4") to change a 5/8" lock into a 7/8" lock, or vice-versa.

The coin door from my Tempest is 5/8".

So these locks only come in different length's, not width's?

[ericball]

3/4" diameter (not the flat, which is 0.635") is the most common, but there are larger & smaller locks available.
