Supra J5 Mortise Universal Keybox

[gswimfrk]

Hello Everyone!!!

I received my Supra boxes in the mail today, the ones with the mortise cylinder hole... and I was wondering if anyone knew which kind of mortise cylinder cam I would need?

I plan on installing some 7pin SFIC cores in it so I would need a 7pin housing. I Just don't know what cam to use? The box says "any standard 1-1/8'' or 1-1/4'' mortise cylinder will work, it did not state what cam. The pack only came with a cover, a box, a spacer ring, a bracket, and a cash box nut. I suspect the cam of the mortise cylinder will lock the cover in place?

Anyone know about these?

Thanks!
