strength of a Domino vs. Clamex

[HowardH]

I have a number of projects coming up where I have used dominos in the past and then clamped everything up.  I have been researching the Lamello Zeta P2 and the Clamex system and wondered if it would have the same strength when used in a outdoor furniture set up. Do they have the sheer strength of the Domino and could they hold up over time when left outside?  This is what I plan on building more of.

Use both.  P14 is only 14mm deep.  It's the bending that's needs to be transferred to the surrounding wood.  I trust the domino more for structure.

edit: I don't have a Zeta, yet.  Been trying to convince myself it's useful... so far only face frames and miters :/

Where I could see the Clamex be most useful is in the vertical back supports and the miters. It would be much easier to put together.

For mitred corners the P system is a 100x easier then dominos.  I always struggled with alignment issues when clamping mitred corners with dominos but with the clamex they just pop together and you're done.  Even adding a few clamps where the connectors are doesn't cause alignment issues.  Strength wise I'd still add dominos beside the clamex connectors for your application.

Clamex or Tenso?

Clamex are the knock-down connectors, Tenso are the snap-together connectors.

I often use them together. The Dominos add are the strength and the Clamex pull the joint together.
I use the Tenso in both glued (as clamps) and unglued for a knock-down situation. The beauty of them is that they are totally invisible, there is no access hole required.
I have put together some pretty large assemblies this way and never had a problem with strength.
