Subal port mount type 3 or 4? - determining

I will email Subal on this if I can't find out but thought someone might know off the top of their head.

How do I work out if I have type 3 or 4 subal housing port mount? From the guide on reef photo (http://reefphoto.com/kb.php?id=21) I would be type 4 according to internal diameter (110mm) but my mount is not tapered like that.

From memory I am type 3 but I can't find any of the original purchase paperwork. I bought the housing early 2009 if that is any help.

Thanks,

Claire

Hi Clare

The date doesn't determine it too clearly - unhelpfully. It could be Type 3 or 4 as, at that date, I think you could choose.

It's the dimension that is the determining factor (no surprise!). Unless anyone else knows differently, I think you'd have to go with the dimensions on the Reef Photo guide.

(I've got a Type 4 which corresponds with the Reef info - and mine has sloped sides)

Thanks Tim. Annoyingly I went through this before when I bought by dome port but I had an email clear out a while ago and can't find the sale info. I think I will contact subal just to be sure as the flat sides are worrying me.

Hi Claire:

If the internal diameter of your port is 11 cm, then it is a Type 4. Here are two photos of Type 4.

The port ring on your housing may not have the sloping side because the housing is of a smaller size.

Cheers!

Hey Claire

I've just checked my Type 4 and, as KdM and Reef report, from flange edge to flange edge on the Type 4 is 110mm.

No harm at all of course checking with Subal but if the opening it smaller than the 110mm, I reckon you have Type 3.

I've noticed that the more recent bits and bobs, ie EXRs and ports, now have a "/4" on them - which is helpful! So the EXR I got for my Tokina says "13/4". Maybe I can go now back to weeding my emails out again too....

(Got a really nice Subal ND800 housing for sale if I can tempt you...... Type 4)

Thanks guys. Got confirmation from Subal that it is indeed type 4.
