I believe that's for a double chainring, not a triple......
Triple has a much larger inner chain plate.....

This was factory equipment on my Trek 720 which came with a Sugino triple (48-44-28). Hereís a better angle.

Did FDs come in different sizes when this was made? I've used a number of Suntours on my bike, and they've worked with both double and triple setups. A 1st gen Cyclone now seems to work fine on my half-step + granny gear (28).

Yeah, the SLJs had different cage sizes.

Definitely for a double. You can see examples of the triple version at eBay with its much bigger inner chain plate.....
I have the double version on a few of my 80's C&V French race bikes. That's why I'm familiar with how they look like.

I've got an SLJ 'double' FD on my triplized PX-10 and it's shifting 28/42/45 fine.

Here's a good pic of the triple version.....
The double version usually go for a bit more money out there, at least, per my experience shopping for these FDs through the years....
